Answer 1

The marked price of a watch is Rs.1600. The shopkeeper gives successive discount of 10% and x% to the customer. If the customer pays Rs.1224 for the watch, what is the value of x?
1600*(90/100)*[(100-x)/100] = 1224, or
100-x = 1224*100*100/(1600*90) = 85, or
x = 100–85 = 15%.
Check: 1600*(90/100)*(85/100) = 1224. Correct.
x = 15 %
