Question

A man bought goods worth rs 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 should sell the remaining goods

Step-by-step explanation:

Let say man bought  3x items  of Rs 4500

3x items cost = 4500

=> x items cost = 4500/3 = 1500

1/3 Of 3x = x sold at 10 % loss

loss =(10/100)1500 = 150

gain 20% on the whole transaction

=> 20 % of 4500  =  900

Gain he should get by selling 3x - x = 2x items  = 900 + 150 = 1050

1050 gain from 2x items worth ts 3000

Gain % = (1050/3000) * 100  =  35 %

Answer 2

Answer:

ANSWER

Let the gain percent be x%.

According to the question,

(110% of 3000)+(100+x)% of 3000=125% of 6000

(110×30)+(100+x)×30=125×60

3300+3000+30x=7500

30x=1200

x=40%
