Shanto was asked to find the value of 7/12 of a sum of money. Instead of multiplying the same by 7/12, he devided it by 7/12 and his answer exceeded the correct answer by The correct answer is—

A 48

B 89

C 84

D 69

Solution

Correct Answer: Option C

Sum of money = X taka

7/12 th of the money = (7* X) / 12

Due to Shanto's mistake, he found the value of:

12 / 7 th of the money = (12 * X) / 7

Now,

(12*X)/7 - (7*X)/12 = 95

or, (144X - 49X) / 84 = 95

or, 95X / 84 = 95

or, X = (95 * 84) / 95

or, X = 84
