Some articles were bought at 6 articles for Rs. 5 and sold at 5 articles for Rs. 6. Gain percent is:
30%
33 1 %
3
35%
44%
Answer: Option
Explanation:

Suppose, number of articles bought = L.C.M. of 6 and 5 = 30.

C.P. of 30 articles = Rs. 5 x 30 = Rs. 25.
6

S.P. of 30 articles = Rs. 6 x 30 = Rs. 36.
5

Gain % = 11 x 100 % = 44%.
25

The choice of number is arbitrary....
you can take any number in place of 30..
even if you take 1 you will get the answer.
..by taking 30 calculation will be simpler
