• A. Amita
• B. Balu
• C. Both Amita and Balu, since their rate of typing is same
• D. Can't be determined

Answer 1

The correct option is A

Amita

This is a simple problem which would explain how "rates” are useful. In this case, rates are used to decide whether a person is fit for a job or not.

To solve this we need the ratios of the number of words typed in a certain fragment of time.This ratio (or rate) for

$Amita=\frac{120words}{60seconds}=2$

$Balu=\frac{80words}{50seconds}=1.6$

$\therefore$ Amita types faster than Balu.
