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 the fastest typing speed. Who is more likely to get the job?

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

Answer 1

The correct option is A Amita

This is a simple problem which can 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 is $120$ words/$60$ seconds (= 2 words per second) and for Balu it is $80$ words/$50$ (= 1.6 words per second) seconds.
