Question

Amita and Balu applied for a typing 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 a faster typing speed out of the two. Who would get 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 would explain how "rates” are useful. So useful that sometimes they 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 would be $120$ words/$60$ seconds and for Balu it would be $80$ words/$50$ seconds.
