Question

Seema reads $\frac{1}{5}$ of a book per hour. If she goes to sleep after reading for $2\frac{1}{3}$ hours, how much part of the book is left to be read?

$\frac{8}{15} \\$

$\frac{7}{15} \\$

$\frac{3}{7} \\$

$\frac{1}{5}$

Solution

Correct option is A

Given:

Reading rate per hour =

\frac{1}{5} \\

Time spent reading =

2\frac{1}{3} = \frac{7}{3}

hours
Part of book read =

\frac{1}{5} \times \frac{7}{3} = \frac{7}{15} \\

Part left to be read =

1 - \frac{7}{15} = \frac{8}{15}

Correct answer is

{\frac{8}{15}}
