If 5% more is gained by selling an article for Rs.350 than by selling..

A. Rs. 50
B. Rs. 160
C. Rs. 200
D. Rs. 225

Answer

C. Rs. 200

Solution

Let Cost price of the article be Rs.x

When Selling price is Rs.340 then,
Gain% = (340-x)/x * 100

When Selling price is Rs. 350 then,
Gain% = (350-x)/x * 100

Hence,
Additional % gain= (350-x)/x * 100 – (340-x)/x * 100
Additional % gain= 5=[350−x−340+x] * 100/x [It is given that gain% = 5%]

5x=1000
x=Rs.200

Cost price of article is Rs.200
