Question

A number is mistakenly divided by 5 instead of being multiplied by 5. Find the percentage change in the result due to this mistake.

• A. 96%
• B. 95%
• C. 2400%
• D. None of these

Answer 1

The correct option is A 96%

Let number is 100

It is divided by 5 we get 20

Now actual result should be

$5\times 100=500$

So % change in result

$=\frac{500-20}{500}\times 100=96\%$
