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:

Let the cost price be 100

Marked price is 30% above it or 130.

Discount given is 10% of 130 or 13

Sale price is 130–13 =117

Profit is 17

Profit as percentage of cost is 17/100=17%

Answer 2

Answer:

Let CP = 100.

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

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

Gain = 108 - 100 = 8

%Gain = (8 *100)/100 = 8%.

Short-cut

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

% gain = 8%.

here is your answer
