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)
