In the above Question , the following information is given -

Three fifth of a number is 126.

To find -

Here , we have to find the required number .

Solution -

Here , let us assume that this required number is equal to x.

Now , we are given the following condition -

Three fifth of a number is 126.

Here , the number is X .

Therefore , three fifth of the number must be three fifth of x.

So,

( 3 / 5 ) th of X

But , this is equal to 126.

So, we can write the following -

( 3 / 5 ) × x = 126

=> ( 3 / 5 ) × x × 5 = 126 × 5 = 630

=> 3x = 630

=> 3x ÷ 3 = 630 ÷ 3

=> x = 210 .

Hence , the required number comes out to be 210 .

Hence , Option B is the correct answer .

Verification -

( 3 / 5 ) of 210

=> ( 3 × 210 ) / 5

=> 630 / 5

=> 126
