To find discount when Marked price and Sale price are known (Problem-10: Discount)

Q. A shopkeeper offers a discount of 20% on the cell phone. Find the marked Price of cell phone if its sale price is Rs. 7200.

Given:

S.P = Rs. 7200

Discount = 20 %

 

To Find:

M.P = ?

Solution:

Since 

S.P = M.P - Discount

Where discount is determined on M.P, therefore

Discount = 20 % of M.P

thus

S.P = M.P - 20 % of M.P

S.P = M.P - `frac {20}{100}` M.P

S.P = (1- `frac {20}{100}`) M.P

S.P = (`frac {100 - 20}{100}`) M.P

S.P = (`frac {80}{100}`) M.P

or

M.P = (`frac {100}{80}`) S.P

M.P = (`frac {100}{80}`) Rs.7200

M.P = Rs.9000 ----------------Ans.
