The marked price of an item was Rs. 4000 but the shopkeeper offered a double discount of 5 percent and 7 percent. In how much did he finally sell the item?
Show answer & explanation
Correct answer: B
Explanation
The Correct answer is Option 2 i.e.Rs. 3534.
M.P. = Rs.4000
Double discount = 5% and 7%
Single discount of double discount = x + y + xy/100
⇒ -5 - 7 + 35/100 = -12 + 0.35 = -11.65 [negative sign indicates discount]
Now, according to the question
⇒ 4000 × (100 - 11.65)/100 = 4000 × 88.35/100 = Rs.3534
