A Shopkeeper marks the price of a refrigerator at Rs.
30,000/- and gives a discount of 15%. He also gives a mixer grinder worth Rs. 1,500 free with the refrigerator and actually earns a profit of 20% by selling the refrigerator. Find the cost price of the refrigerator.Solution
S.P = 85% of 30,000 = 25,500  &  Profit = 20% ∴ C.P = 25500
 = 21,250 Since mixer grinder worth Rs. 1,500 is also given, ∴ C.P of the refrigerator = 21,250 – 1,500 = Rs.19,750
