Question

If $100$ is increased by $40\%$ and then decreased by $40\%$, then the resulting number is

• A. $140$
• B. $56$
• C. $84$
• D. $40$

Answer 1

Answer: (C)

$84$

If $100$ is increased by $40\%$ then the number will be $\frac{100\times 140}{100}=140$.

Now if $140$ is decreased by $40\%$ then the resulting number is $\frac{140\times 60}{100}=84.$
