Answer 2

Given:

Cost of 1 dozen bananas is ₹18.

We are asked to find the cost of 30 bananas.

Solution:

1 dozen of bananas = 12 bananas.

So, the cost of 12 bananas is ₹18.

12 bananas = ₹18.

30 bananas = ₹x.

12/30 = 18/x.

12x = 540.

x = 540/12.

x = ₹45.

Therefore, the cost of 30 bananas is ₹45.
