Question

the market price of a radio is 20% more than its cost price the radio is sold to make the profit of 10% .If the profit is Rs 80 what is the market price .find it ​

Answer 1

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%.
