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. Who is faster ?

• 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

Ratio of Amita's number of words /seconds = $\frac{120}{60}$ = 2

Ratio of Balu's number of words/seconds = $\frac{80}{50}=\frac{8}{5}$

Hence Ratio of Amita's typing skills to Balu's typing skills = 2 : $\frac{8}{5}$

Simplifying we get ; 10 : 8 = 5 : 4

Hence Amita is faster
