Question

A boy reads $10$ pages in $15$ minutes, what will be the total number of pages read by him in $1\frac{3}{4}$ hours?

• A. $35$
• B. $70$
• C. $350$
• D. $110$

Answer 1

The correct option is B $70$

No. of pages read in $15$ minutes $=10$

No. of pages read in $1$ minutes $=\frac{10}{15}$

No. of pages read in $1\frac{3}{4}$ hours $=\frac{10}{15}\times 1\frac{3}{4}\times 60$

$=\frac{10}{15}\times \frac{7}{4}\times 60$

$=70$ pages.
