8. A student multiplied 7236 by 65 instead of multiplying by 56. By how much was his answer greater than the correct answer? (Hint: Do you need to do both the multiplications?)

Answers (1)

Given,

The student multiplied 7236\ by\ 65 instead of 56.

Wrong answer = 7236 \times 65

Correct answer = 7236 \times 56

\therefore The difference in the answers = 7236 \times 65 - 7236 \times 56

= 7236 \times (65 - 56) = 7236 \times 9

= 65124

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