A television manufacturer earns 20 percent profit by selling each TV set for Rs. 14,400. If the production cost is increased by 15 percent, what should be the new selling price of a TV set so as to gain a profit of 15 percent?
A15870 ✓ Correct
B13800
C12000
D15000
Correct answer: (A) 15870 — The answer is 15870.
Explanation
★The answer is 15870.
★At a 20 percent profit the selling price of 14400 gives a cost of 12000.
★Raising the cost by 15 percent makes it 13800.
★A 15 percent profit on 13800 adds 15 percent to it.
★So the new selling price is 13800 times 1.15.
★That equals 15870.
★So the answer is 15870.
