Question

The cost of 4 dozen bananas is rupee 60. How many bananas can be purchased for rupee 12.50?

Answer 1

10 bananas

Explanation:

In ₹60, we can purchase 4 dozen bananas

=> 4×12

=> 48 bananas

In ₹1, we can purchase:-

`(48)/(60)`bananas

In ₹12.50, we can purchase:-

`(48)/(60) * 12.50`

`= > (48 * 1250)/(60 * 100)`

`= > (8 * 125)/(100)`

By reducing to lowest terms, we get,

`10`

Hence, 10 bananas can be purchased for ₹12.50

Answer 2

10 bananas

Explanation:

Compare same things in the same order to write a proportion

(fraction = fraction)

bananas/rupees

=4dozen/R60

=4(12)/R60

=48/60

=4/5

The question says

bananas/rupees

=unknown/R12.5

4/5 = x/12.5

crossmultiply

4(12.5) = 5x

50 = 5x

divide by 5

10 = x

You can buy 10 bananas for R12.5
