Question

Amita and Balu apply for a typist's job. Amita can type 120 words per minute while Balu can type 80 words in 50 seconds. The employer wants to select the one with the fastest typing speed. Who gets the job?

• 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 explains how 'rate' is useful. So useful that sometimes it helps decide whether a person is fit for a job or not.

To solve this question, we need the ratios (or rates) of the number of words that Amita and Balu can type in a certain period of time.

Rate for Amita = $\frac{120\text{words}}{60\text{seconds}}$
= 2 words per second

Rate for Balu = $\frac{80\text{words}}{50\text{seconds}}$
= 1.6 words per second

Therefore, Amita types faster than Balu.
