Vikram allows two successive discounts of 20% and 10% on the marked price of a book, which is equal to a single discount of Rs.252. Then how much, profit will Vikram get, on that book, if the cost price is Rs.600 ?

Rs.48

Successive discount =  x + y - \(\frac{x × y}{100}\)

Successive discount =  20 + 10 - \(\frac{20 × 10}{100}\) = 28%

28% of the MP = 252

72% of the MP = 648

CP = 600

Profit  = 648 - 600 = 48
