1. ## Financial Maths Question Help Please !!

Hi guys,

I need help with the following q. please:

A retailer offers a discount of 20% off the marked price of all TV sets. This means that his percentage profit (on the cost price) has been reduced to 10%. What was the original percentage profit?

Thanks

Let cost price = C and original marked price = P

.: discounted selling price = 0.8 P = 1.1 C

.: P = 1.1/0.8 C = 1.375 C

.: original percentage profit = 0.375 x 100% = 37.5%
