Question

Find the resulting quantity when a speed of $600km/h$ is increased by $12\frac{1}{2}\%$.

Answer 1

Step : Finding the resulting quantity

Given, speed of $600km/h$ is increased by $12\frac{1}{2}\%$

So, $12\frac{1}{2}\%$ of $600km/h=\frac{25}{2}\%$ of $600km/h$

$=\frac{25}{2\times 100}\times 600$

$=25\times 3=75km/h$

Hence, the increased speed

$=600+75=675km/h$.

Hence, the resulting speed is $675km/h$.
