A shopkeeper marked an article at 50% above its cost price and sold it after giving two successive discounts of 10% and 20% respectively. If the shopkeeper gets the profit of Rs.960, then find the marked price of the article?
a) Rs.18000
b) Rs.20000
c) Rs.15000
d) Rs.22000
e) Rs.12000
Sol:
CP * 150/100 * 90/100 * 80/100 = CP + 960
0.08 CP = 960
CP = 12000
MP = 12000 * 150/100
= 18000
