Answer 2

Given that Manish multiplied

$100 \: by \: 89$

instead of multiplying

$100 \: by \: 79$

We need to find how much was his answer greater than the correct answer.

The answer Manish got by multiplying

$100 \: and \: 89 \: is \\ 100 \times 89 \\ = 8900$

The answer Manish needs to get by multiplying

$100 \: and \: 79 \: is \: \\ 100 \times 79 \\ = 7900$

The difference of Manish's answer and correct answer is

$8900 - 7900 \\ = 1000$

Therefore, his answer was 1000 units greater than the correct answer
