Question

A man bought goods worth ₹4500 and sold 1/3 of the goods at a loss of 10%.At what gain percent should he sell the remaining goods so as to gain 20% on the whole transaction?

Answer 1

at 35% gain he has to sell the remaining goods
let the quantity of the goods is x
now the cost of x is 4500
now the cost of x/3 should be 1500
but he sold it in 10% loss, so now the price is 1350
now in gross 20% gain, the coat of x will be (4500*120)/100= 5400,
now the cost of remaining part should be (2*1500)/3=3000
ok, due is 5400-1350=4050
now the gain is 4050-3000=1050

now the gain is (1050/3000)*100= 35%
