Question

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

Answer 1

10 bananas

Step-by-step explanation:

In ₹60, we can purchase 4 dozen bananas

=> 4×12

=> 48 bananas

In ₹1, we can purchase:-

$\frac{48}{60}$bananas

In ₹12.50, we can purchase:-

$\frac{48}{60} \times 12.50$

$= > \frac{48 \times 1250}{60 \times 100}$

$= > \frac{8 \times 125}{100}$

By reducing to lowest terms, we get,

$10$

Hence, 10 bananas can be purchased for ₹12.50

Answer 2

Answer:

10 bananas

Step-by-step 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
