GIVEN

2/5th of a number exceed the 1/7th of the same number by 36.

TO FIND

The unknown number

SOLUTION

Let the number be x

According to the Question ,

2/5 of x - 1/7 of x = 36

=> 2x/5 - x/7 = 36

=> (14x - 5x)/35 = 36

=> 9x = 36 × 35

=> x = 4 × 35

=> x = 140

VERIFICATION

LHS =

2/5 th of 140 = 2/5 × 140 = 56

1/7 th of 140 = 1/7 × 140 = 20

Now difference is 56 - 20 = 36

= RHS

(Hence our Answer is Correct)
