Question

A boy types 180 words in 2 minutes. How many minutes would he take to type 900 words ?

• A. 10 minutes
• B. 20 minutes
• C. 15 minutes
• D. 25 minutes

Answer 1

The correct option is A

10 minutes

Let the time taken by the boy to type 900 words be x mins.

Hence, we have $\frac{180}{2}=\frac{900}{x}$

$x=\frac{900\times 2}{180}$

Thus, x= 10 minutes
