Question

A student multiplied a 220 by 75 and instead by multiplying by 57 by how much was his answer greater than the correct answer

Answer 1

◆Answer◆

Solution

Multiplied 220 with 75 instead of multiplying 220 with 57.

Product got by multiplying 220 with 75 = 220×75 = 16,500.

Original Product that needed to be finalized = 220×57 = 12,540.

How much was his answer greater than the correct answer = 12,540 subtracted from 16,500

= 16,500-12,540.

=3,960

Therefore, his answer was greater than the correct answer by 3,960.
