Solution
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 120words60seconds=2 and for Balu it would be 80words50seconds=1.6. Therefore, Amita types faster than Balu.
