Correct Answer - Option 3 : Rs. 517
Given:
The cost price of 7 pens at the rate of 8 each,
The cost price of 5 books at the rate of Rs. 74 each,
The cost price of 7 maps at the rate of Rs. 5 each
And the cost price of 8 notebooks at the rate of Rs 7 each.
Calculation:
The cost price of 7 pens = 7 × 8 = 56
The cost price of 5 books = 74 × 5 = 370
The cost price of 7 maps = 5 × 7 = 35
The cost price of 8 notebooks = 8 × 7 = 56
According to the question,
Sum of total money = 56 + 370 + 35 + 56 = 517
∴ Pappu has to pay Rs. 517 to the shopkeeper.
