# Cost of 4 dozen bananas is ₹ 180. How many bananas can be purchased for ₹ 90?

**Solution:**

Let's use the concept of the unitary method.

From the given data,

The number of bananas bought for ₹ 180 = 4 dozens

4 dozens = 4 × 12 = 48 bananas [Since 1 dozen = 12 units]

So, the number of bananas bought for ₹ 1 = 48 / 180

Therefore, number of bananas bought for ₹ 90 = (48 / 180) × 90 = 24 bananas

Thus, 24 bananas can be purchased for ₹ 90
