Question

a merchant has 1000 kg of sugar part of which he sells at 8% profit and the rest at 18% profit.
He gains 14% on the whole. The quantity sold at 18% profit is

Answer 1

Gain = 14% on whole

ratio of 1st one = 18 - 4 = 4

ratio of 2nd one = 14 - 8 =6

Ratio of 1st and 2nd = 4 : 6 i.e 2 :3

So, Quantity of 2nd part = 1000 * 3/5 
                                         = 600
