Question

A student multiplied 7236 by 65 instead of multiplying by 56 how much was his answer greater than the correct answer

Answer 1

7236 * 65 = 470340
7236 * 56 = 405216

470340 - 405216 = 65124

Answer 2

Difference between 65 and 56 i.e (65 – 56) = 9

The difference between the correct and incorrect answer = 7236 × 9 = 65124

Hence, by 65124, the answer was greater than the correct answer
