Answer 2

Given:

The cost of 1 dozen bananas is ₹ 30.

The cost of 6 oranges is ₹ 18.

To find:

The ratio of the cost of a banana to the cost of an orange.

Solution:

The cost of 1 dozen bananas is ₹ 30.

One dozen have 12 bananas.

The cost of one banana = $\frac{30}{12}$

The cost of one banana = ₹ $\frac{5}{2}$

The cost of 6 oranges is ₹ 18.

The cost of one orange = $\frac{18}{6}$

The cost of one orange = ₹ 3

The ratio of the cost of a banana to the cost of an orange = $\frac{\frac{5}{2} }{3}$

The ratio of the cost of a banana to the cost of an orange = $\frac{5}{2}$ × $\frac{1}{3}$

The ratio of the cost of a banana to the cost of an orange = $\frac{5}{6}$

The ratio of the cost of a banana to the cost of an orange is 5:6

Final answer:

The ratio of the cost of a banana to the cost of an orange is 5:6
