Question

At a stretch, Rashi can study for 3 hours, while Rashid can study for 5 hours. For how many more hours can Rashid study than Rashi at a stretch? Express in terms of percentage.

Answer 1

Number of hours Rashi can study at a stretch = 3
Number of hours Rashid can study at a stretch = 5
So, number of hours Rashid can study more than Rashi at a stretch = 5 - 3 = 2
In terms of percentage, it is given by,

$\frac{\text{Extra hours}}{\text{Number of hours Rashi can study at a stretch}}\times 100$

On substituting the values we get,

$\frac{2}{3}\times 100=66.66$%
