Identifying Tens in a Number
Here
is a number. In
is at tens place. Second digit from right is the digit at tens place. For example,
In
the 2nd digit from right is
and hence, it is the digit at tens place. In this case it is also saidhas tens.
In
the 2nd digit from right.
is
and this is the reason it will be called tens place digit in. This is also said thathastens.

Numbers and Their Name
Let us look at the following patterns:

| Number Name | One | Two | Three | Four | Five |
Fill the blank box with one of the following options:
| One | Two | more...
 Counting in Twenties
Look at the following:
One twenty = 1 twenty =
Two twenties = 2 twenties =
Three twenties = 3 twenties = 
Five twenties = 5 twenties =
Twelve twenties = 12 twenties = 
Now, it is clear that
One twenty is one fold of
Two twenties is twofold of
Three twenties is three fold of
Five twenties is fivefold of
Twelve twenties is twelve fold of
Trick:
While counting in twenties, just double the number of times the twenty to be counted and put it in the left side, the word twenty/twenties written in the right side will be replaced by a single zero (0).
(A) 
Here, we double the two that becomes and put it in the left while the word twenties written in the right get replaced by zero (0).
(B) 
Here, we double the five that becomes and put it in the left while the word twenties written in the right side get replaced by zero (0). Clearly counting in 20's goes as: 20, 40, 60, 80, 100, 120 ..........and so on.
 Four twenties
(a) 140
(b) 80
(c) 40
(d) 60
Answer: (b)
Explanation
4 twenties is four fold of 20 = 80.
It is clear from the following diagram:
Option (A) is incorrect because it is clear from the following diagram that 140 is equal to seven twenties:
Option (C) is incorrect because it is clear from the following diagram that 40 is equal to two twenties:
Option (D) is incorrect because it is clear from the following diagram that 60 is equal to three twenties:
Counting in twenties is given below. Fill the blank box with suitable number.

Counting in Tens
Look at the following:
One ten = 1 ten =
Two tens = 2 tens =
Three tens = 3 tens =
Ten tens = 10 tens =
Twelve tens = 12 tens =
Now, it is clear that,
One ten is one fold of
Two tens is twofold of
Three tens is three fold of
Ten tens is tenfold of
Twelve tens is twelve fold of
Trick:
Just put a single zero (0) in place of ten
From the above given explanation, it is clear that while counting in tens, put number left side and a single zero (0) in the right side.
(A) 
(B) 
Now, it is clear that counting in 10's goes as:
10, 20, 30, 40, 50, 60, 70, 80, 90, 100 ...................... so on.
Five tens = ?
(a) 40
(b) 50
(c) 60
(d) 80
Answer: (b)
Explanation
Option (B) is correct because it is clear from the following diagram:
Therefore, option (b) is correct and rest of the options is incorrect.
Option: (A) is incorrect as
