Cost of 4 dozens bananas is ₹180. How many bananas can be purchased for ₹90?
Share
Cost of 4 dozen bananas = ₹180
Cost of 48 bananas = ₹180 [4 dozen = 4 x 12 = 48]
∴ From ₹180, number of bananas can be purchased = 48
∴ From ₹1, number of bananas can be purchased = 48/180=4/15
∴ From ₹90, number of bananas can be purchased = 4/15×90=24
= 24 bananas
Thus, 24 bananas can be purchased for ₹90.
