Question

The marked price of a radio is 20% more than its cost price. If a discount of 10% is given on the marked price, find the gain percent. ​

Answer 1

Answer:

gain percent is 8

Explanation:

Let CP = 100

Then, MP = 100 + 20% of 100 = 120

Now, SP = 120 - 10% of 120 = 108

Gain = 108 - 100 = 8

%Gain = 8×100100

= 8%

Short-cut

100(CP) == 20%(up) ⇒ 120(MP) == 10%(disc.) ⇒ 108

% gain = 8%
