The marked price of a watch is Rs.1600. The shopkeeper gives two successive discounts to the customer, the first being 10%. If the customer pays Rs1224 for the watch, the second discount is,
5%
After the first discount of 10% on Rs.1600, the sale price drops to,
Rs.1600− Rs.160 = Rs.1440
As the customer pays finally after the second discount, Rs.1224, the second discount amounts to,
Rs.1440−Rs.1224 = Rs.216
This discount is on the sale price of Rs.1440. So the percentage discount is,
2161440×100 = 5%.
