Raghav went to a shopping mall to purchase clothes. He had two coupons with him, but only one can be used on a single day. Using the first coupon, a total discount of 30% could be obtained on the total amount. Using the second coupon, he will get 80% off on the price of the costliest shirt if he buys at least 3 shirts. What is the price at which Raghav can purchase 3 shirts at a minimum price if the prices of the three shirts are Rs.1,250, Rs.1,540 and Rs.1,375?

Rs.2,915.50

We know that,

Marked price × (100 - Discount)% = Selling price

We have,

The prices of the three shirts are Rs. 1250, Rs. 1540 and Rs. 1375

According to the question,

For 30% discount:

Actual cost price = (1250 + 1540 + 1375) × 70% = 4165 × 70% = 2915.5

For 80%  off on the price of the costliest shirt:

Actual cost price = 1250 + 1540 × 20% + 1375

= 1250 + 308 + 1375 = 2933
