Problems Based on Profit and Loss

PROBLEM:11 A shopkeeper has 50 kgs of rice. He sells a part of it at 20% profit and the rest at 40% profit. If he gains 25% on the whole, find the quantity of each part Soln: 20% 40% 25% 15% 5% Ratio 3:1 So quantity sold at 20% profit= (%)*50=37.5 kgs And quantity sold at 40% profit= 50-375-12.5 kgs.
