Question

Amit ate 10 mangoes in 20 mins while Raj ate 5 mangoes in 15 mins.The ratio between the number of mangoes eaten by Raj in a minute to that of Amit is.

• A. 3 : 2
• B. 2 : 3
• C. 4 : 3

Answer 1

The correct option is B 2 : 3

Given,
Number of mangoes eaten by Amit in 20 mins = 10
$\therefore$ In 1 minute, he'll eat $=\frac{10}{20}=\frac{1}{2}\text{mangoes}$

Again,
Number of mangoes eaten by Raj in 15 mins = 5
$\therefore$ In 1 minute, he'll eat $=\frac{5}{15}=\frac{1}{3}\text{mangoes}$
​​​​
Therefore, the ratio of number of mangoes eaten by Raj to that of Amit is
$=\frac{1}{3}:\frac{1}{2}$​​​
$\text{or,}\frac{\frac{1}{3}}{\frac{1}{2}}=\frac{2}{3}$
or, 2 : 3
