Question 55

While selling a watch, a shopkeeper gives a discount of 15%. If he gives a discount of 20% he earns Rs.51 less a profit. What is the original price of the watch ?

Solution

let the marked price of the watch be MP. So the selling price = .85 MP

Profit = .85 MP - CP

If the discount = 20%, selling price = .8 MP

Profit = .8 MP - CP

But (.85MP - CP) - (.8MP - CP) = 51

So, .05 MP = 51

or MP = 1020
