Question

Cost of 4 dozens bananas is Rs.60. How many bananas can be purchased for Rs.12.50?

Answer 1

Cost of 4 dozen bananas = Rs.60 

Cost of 48 bananas = Rs.60 [4 dozen = 4 x 12 = 48] 

∵ From Rs.60, number of bananas can be purchased = 48 

From Rs.1, number of bananas can be purchased = 48/60 = 4/5 

From Rs.12.50. number of bananas can be purchased = 4/5 x 12.50 = 4/5 x 1250/100 = 10 bananas
