* Adding Cost of Things       This is grouping of the costs of two or more things converting them into single money value. If cost of one apple =rupees and cost of one banana =rupees then total cost of both the fruits = cost of one apple + cost of one banana =rupees +rupees.     Or     If cost of one pen =paise cost of two pencils =paise Cost of one rubber =paise then cost of one pen + cost of two pencils + cost of one rubber. =paise +paise +paise =paise.   Or             4 rupees is the cost of a toy and 3.rupees is the cost of a pen. What is the cost of one toy and one pen? (a) 7 rupees                        (b) 8 rupees                       (c) 6 rupees                        (d) 9 rupees   Answer: (a)   Explanation Cost of one toy + cost of one pen =rupees +rupees =rupees.   Or            The cost of one copy is 5 rupees and the cost of 2 books is 6 rupees. What is the total cost of one copy and 2 books? (a) 15 rupees                                     (b) 9 rupees (c) 11 rupees                                      (d) 2 rupees     Answer: (c)   Explanation Option (c) is correct because cost of one copy + cost of 2 books   = 5 rupees + 6 rupees = 11 rupees. Or                
  • Money is paid while buying things and it is received on selling things.
  • Rupees and paise are the units of money.
  • Coins are metal form of money.
  • Notes are paper form of money.
  • Coins and notes are also known as currencies.  
     
  • In India 1 paisa coin was used. 1000 note has been introduced few years back.

*    Identifying Coins     All coins are made up of metal. In India 50 paise, 1 rupee, 2 rupees, 5 rupees and 10 rupees coins are there in circulation. Just see the 50 paise coin given below: 50 paise       2 rupees        It is clear from the pictures of the coins given above that denomination of coins is written on it. Therefore, when we see a coin, we find the denomination given on it so that the coin can be identified easily.             Which one of the following options has 5 rupees coin? (a)                                    (b) (c)           (d)     Answer: (a)            Which one of the following is correct? (a) 5 paise                         (b) 1 rupees       (c) 2 rupees                     (d) 2 rupees          Answer: (c)

* Concet of Money   We all are familiar with Money. In India or anywhere in the world money is available in the form of coins and notes. We pay money while purchasing any things and receive money by selling goods.     Further it must be noted that money in India is counted in terms of paise and rupees. Let's remember the following: 100 paise      = 50 paise        =            25 paise        =                                           Half of the half rupee 20 paise        =                                            One of 5 parts of a rupee 10 Paise       =                                             One of the 10 parts of a rupee 5 Paise     =                                           One of the 20 parts of a rupee One 1 rupee    =                                                            1 rupee Two 1 rupee       =                                               1 rupee                1 rupee Three 1 rupee   =                                               1 rupee    1 rupee      1 rupee and so on One 2 rupees     =                                                                                           2 rupees Two 2 rupees     =                                                                            2 rupees         2 rupees Three 2 rupees =                                                                 2 rupees   2 rupees   2rupees and so on One 5 rupees     =     more...

*     Reading Time from a Clock     When the minute hand is atthen the actual time is the number that is indicated by the shorter or hour hand. For example, just see the following:     Here the longer or the minute hand is at 12 and hour or shorter hand indicates 9. Therefore, the time is 9 or 9 O ' clock. Similarly, in the clock shown below. The time is 4 or 4 O'clock.     When the minute hand is at any number we do counting in 5 like. If minute hand is atit showsminutes.     If minute hand is atit showsminutes.     If minute hand is atit showsminutes.     And this process goes on Let's look at the picture given below:     Here the shorter or hour hand stays between &while minute hand indicates. So the time is 01 : 20 . When we do counting infor it goes asand. Thus the longer hand indicatesminutes. It does mean the actual time is 1: 20 and we read it as 20 minutes past 1. Similarly if shorter or hour hand is somewhere between&and minute hand is at 5 then the time is 2:25 and it will be read as '25' minutes past 2.     When the longer or minute hand is at, the time is read as the half past the hour. Let's see the picture given below:     Here the hour or shorter hand is somewhere between& and minute hand is at. Therefore, the time is 1: 30 and it is read as 'half past 1' Similarly if the hour hand is somewhere between&and minute hand is atthen the actual time is 4 : 30 and it is read as 'half past 4'           more...

*  Time Indicating Watches       Let's see the face of the clock given below:       In the above mentioned clock/the numbertoare marked. The space between two consecutive numbers is divided intoequal parts. Thus the face or dial of the clock is divided intosmall divisions. This is also clear from the picture of the clock that it has two hands. One is the shorter hand that is called hour hand and the other is the longer hand that is called minute hand. The minute hand moves from one small division to another small division in one minute orseconds. It means it goes around the dial of the clock in hour.       As minute hand covers two small divisions inhour therefore,hour= minutes It must be noted also that the minute hand moves from one number to another inminutes.     * Important Points   
  • The hour hand moves from one number to the next in 1 hour.
  • The hour hand takes two complete rounds in a day.
  • The hour hand takes 12 hours to complete one round.

*  Knowing Time     Knowing time means knowing period or duration of a certain event. For example, A man goes to a certain distance inminutes, then we can say that he takeshour and one hour is equal tominutes.     Let's take another example: If one minute is taken to cook Maggi then time taken in seconds is equal toseconds.            Which one of the following represents 3 hours? (a) 60 minutes, 60 minutes (b) 60 minutes, 60 minutes, 60 minutes (c) 60 minutes, 60 minutes, 60 minutes, 60 minutes (d) 60 minutes     Answer: (b)       Jennifer takes one minute to eat a bread while Steve takes 4 minutes to eat a bread. Who takes more time? (a) Jennifer takes more time (b) Steve takes less time (c) Jennifer and Steve take equal time (d) Jennifer takes less time and Steve takes more time.   Answer: (d)

*   Hours, Minutes and Seconds     Hours, minutes and seconds are units for the measurement of time. For example we can say: hours;minutes;seconds Now just remember hours =day hour    = minutes minute =seconds Henceday =hours ortime ofhours   Therefore, days    =times ofhours days    =times ofhours days    =times ofhours and so on.   Similarly, hour=minutes or 1 time ofminutes hours  =times ofminutes hours  =times ofminutes and so on. Againminute =seconds ortime of seconds Hence,minutes =times ofseconds minutes =time ofseconds and so on.            24 hours + 24 hours = ? (a) 4 days                                             (b) 2 days (c) 3 days                                             (d) 5 days     Answer: (b)   Explanation   hours +hours=day+day=days        5 minutes means ___times of 60 seconds. (a) 5                                                       (b) 4 (c) 6                                                       (d) 8     Answer: (a)   Explanation minute =time ofseconds Hence, minutes =times ofseconds Let's check it: minutes can be written as  
1 Minute 1 Minute more...
*  Introduction     A day is divided into hours and an hour is divided into minutes and a minute is divided into seconds. See the following examples: A train reaches Patna in one day hence 'one day period' is a time. The examination time is forhours hence hour is a period of time.  

*  Ascending and Descending Order     Numbers can be arranged in ascending or descending order. In other words you can say that numbers can be arranged from smallest to greatest or greatest to smallest.     * Ascending Order In ascending order numbers are arranged in the order from smallest to greatest. For example: are in ascending order.       Arrange the following numbers in ascending order: The correct answer is. To solve this first we write smallest number that is. Then again write the smallest number from the remaining numbers that is and thus continue in the same way. The numbers are arranged in the ascending order.       Arrange the following numbers in ascending order: The correct answer is To solve this first we write smallest number that is. Then again write the smallest number from the remaining numbers that is and thus continue in the same way. The numbers are arranged in the ascending order.              Arrange the following numbers in ascending order: 65, 98, 58, 49, 36, 62. (a) 36,49,58,62,65,98                       (b) 36,49,58,98,65,62 (c) 49,36,58,62,65,98                       (d) 36,49,62,58,65,98     Answer: (a)      Arrange the following numbers in ascending order: 89, 91, 87, 86, 95, 79 (a) 79,86,87,89,95,91                       (b) 79,86,87,91,89,95 (c) 89,86,87,79,91,95                       (d) 79,86,87,89,91,95     Answer: (d)       * Descending Order In descending order numbers are written from greatest to smallest. For example:are in descending order.         Arrange the following numbers in descending order:   The correct answer is To solve this first we write greatest number that is. Then again write the greatest number from the remaining numbers that is and thus continue in the same way. The numbers are arranged in the descending order.       Arrange the following numbers in descending order: The correct answer is To solve this first we write greatest number that is. Then again write the greatest number from the remaining numbers that is and thus continue in the same way. The numbers are arranged in the descending more...

*     Comparison of Images (Size)     The comparison is done through pictures.   * Size Comparison Let's understand it through an example:     In the above mentioned pictures (a) is smaller and (b) is bigger. Therefore, (a) is smaller in comparison of (b) while (b) is bigger in comparison of (a). Thus we can present it as:     Take another example: Here again picture (a) is smaller in comparison of (b) and picture (b) is bigger in comparison of (a) Thus we can present it as        *   Comparison of (Number) Images Just see the two groups of pictures given below:     Here group A has four keys and group B has two keys. Therefore, group A is greater than group B and this can be presented as:   Take another example:     Here box (a) has 6 bowls while (b) has 3 bowls. Thus box (a) has more number of bowls in comparison of box (b). It can be presented as:          Which one of the following is not true? (a)                        (b) (c)               (d)     Answer: (c)   Explanation Picture in left is smaller than the picture in right.              The following picture is greater than which one of the following options? Calculate in term of numbers.   (a)                   (b) (c)                   (d)     Answer: (d)
