Question

Mona reads 10 pages each of Math, Chemistry, Physics and Biology book everyday. If each book contains 150 pages, what fraction of the total pages does Mona read in 10 days?

• A. $\frac{3}{2}$
• B. $\frac{2}{3}$
• C. $\frac{1}{4}$
• D. $\frac{6}{5}$

Answer 1

The correct option is B

$\frac{2}{3}$

Total subjects = 4 (Math, Chem, Phy, Bio)

Total number of pages of all subjects = $4\times 150=600$

Number of pages Mona reads in each subject = 10

Total number of pages Mona reads each day = $4\times 10=40$

Hence, number of pages Mona reads in 10 days = $10\times 40=400$

Fraction of pages Mona reads in 10 days = $\frac{400}{600}=\frac{2}{3}$
