Question

Aman multiplied $6241$ by $64$ instead of multiplying by $46$. By how much was his answer greater than the correct answer?

Answer 1

Find the difference of Aman's answer and correct answer:

Aman multiplied $6241$ by $64$:

$\Rightarrow 6241\times 64=399424$

But he have to multiply $6241$ by $46$.

$\Rightarrow 6241\times 46=287086$

Correct answer is $287086$.

Incorrect answer is $399424$.

Thus, the difference is given by:

$=$Incorrect answer $-$Correct answer

$$\begin{gathered} =399424-287086 \\ =112338 \end{gathered}$$

Hence, by $1,12,338$ his answer is greater than the correct answer.
