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 more...

    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) more...

 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        =                  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.   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 more...

  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 more...

   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 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 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 more...
