Correct Answer: Rs. 48
Solution : Given: Successive discounts of 20% and 10% = Rs. 252 Single equivalent discount = $(a+b-\frac{a×b}{100}$)%, where $a$% and $b$% are successive discounts. ⇒ Single discount equivalent to 20% and 10% = $20+10-\frac{20×10}{100}$ = 28% So, 28% of the marked price = Rs. 252 ⇒ Marked price = $\frac{252}{0.28}$ = Rs. 900 Now, Selling price = Marked price – Discount = 900 – 252 = Rs. 648 Now, the Cost price = Rs. 600 Profit = Selling price – Cost price = 648 – 600 = Rs. 48 Hence, the correct answer is Rs. 48.
