Question

A banana costs Rs 24 per dozen while 10 apples are sold for Rs 100. Then how many times an apple is costlier than a banana.

• A. three times
• B. four times
• C. five times
• D. They have the same price

Answer 1

The correct option is C

five times

Given,

1 dozen = 12

The cost of 12 banana is Rs 24, then the cost of one banana is $\frac{24}{12}=2$
The cost of 10 apples is Rs 100, then the cost of one apple is $\frac{100}{10}=10$

The cost of one banana is equal to Rs 2 while the cost of one apple is Rs 10.
The ratio of cost of the apple to banana
= $\frac{costofoneapple}{costofonebanana}$
= $\frac{10}{2}$ = 5

$\therefore$ Apple is five times costlier than the banana.
