The cost of one dozen bananas is Rs. 5. The cost of one dozen oranges is Rs. 75. What will the cost of one and a quarter dozen bananas and three-fourth dozen oranges? Correct Answer Rs. 62.50

The cost of one dozen bananas = Rs. 5

One and a quarter dozen means 12 + 1/4 × 12 = 15

So, cost of one and a quarter dozen bananas = 15 × 5/12 = Rs. 6.25

The cost of one dozen oranges = Rs. 75

So, cost of three-fourth dozen oranges = 12 × 3/4 × 75/12 = Rs. 56.25

So, total cost = 6.25 + 56.25 = Rs. 62.50
