The marked price of an item was Rs. 100000, but the shopkeeper offered a double discount of 20 percent and 10 percent. At what price did he finally sell the item?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Rs. 72000
The marked price of the item = Rs. 100000
The shopkeeper offers a double discount of 20% and 10%.
Total discount = a + b - (a × b)/100 = 20 + 10 - 20(10)/100 = 28%
Price at which he finally sells the item = 100000 - 28% of 100000 = 100000 - 28(100000)/100 = 100000 - 28000 = Rs. 72000
