Question

goods worth RS 6000 are purchased what should be the selling price to earn a profit of 12 %​

Answer 1

Answer:

Let A & B denote the two halves of total goods, where cost-prices of both A & B are (Rs.6000 / 2 =) Rs.3000. Let Sa & Sb denote the sell-prices of A & B respectively.

Let A was sold at a gain of 12%. So we get,

Sa = (1 + 0.12)*3000 = 1.12*3000 = 3360 …… (1)

Let the remaining half B was sold at a gain of X%. So we get, Sb = (1 + X/100)*3000 …… (2)

It is given that the shopkeeper gets 18% profit on the whole. So we get,

Sa + Sb = (1 + 0.18)*6000 = 1.18*6000 = 7080

or 3360 + (1 + X/100)*3000 = 7080 [from (1) & (2)]

or (1 + X/100)*3000 = 3720 or 1 + X/100 = 3720/3000 = 1.24 or X/100 = 0.24 or X = 24

Therefore the remaining half B was sold at a gain of 24%. [Ans]
