Question
A boy was asked to find 7/16 of a number. Instead, he found 3/4 of it. His answer was 110 greater than the correct answer. What is the number?
Solution
ATQ, Let the number = x Wrong answer − Correct answer = 110 x × 3/4 − x × 7/16 = 110 (3/4 − 7/16) x = 110 = ((12/16 − 7/16)) x = 110 (5/16) x = 110 x = 110 × 16 / 5 x = 22 × 16 = 352 So, the number = 352.
