Explanation / Answer

Let the cost price be c.

The price after markup is c + (150/100)c = 2.5c

The price after first discount = 2.5c - (15/100)2.5c = 2.125c

The price after second discount = 2.125c - (35/100)2.125c = 1.38125c

Price after coupon discount = 1.38125c - (10/100)*1.38125c = 1.243125c.

Store's profit = 1.243125c - c = 0.243125c

Profit percentage = 0.243125c/c * 100 = 24.31%.
