A merchant has 1000 kg of sugar, part of which he sells at 6% profit and the rest at 16% profit. He gains 108% on the whole. The quantity sold at 16% profit is:
OPtion
1) 900 kg
2) 100 kg
3) 700 kg
4) 300 kg
5) 600 kg
6) 400 kg
7) 200 kg
8) 800 kg
9) 500 kg
10)250 kg
Solution
(Quantity of Cheaper)/(Quantity of Dearer) = (Price of Dearer - Mean Price)/(Mean Price - Price of Cheaper)
(Quantity of Cheaper)/(Quantity of Dearer) = (116 - 108)/(108-106) = 8/2 = 4/1
Total Quantity = 1000 KG
The quantity sold at 16% profit is = (1/(4+1)) * 1000 = 200
