Question

A man sells 12 articles for rs. 80 gaining 100/3 % . Find the number of articles bought by the man for rs 90.

Answer 1

Let c.p be x

S.p = x + 1/ 3 x

100/ 3 x can be written as 1/3 x

X /3 + x= 80

4/3 x =80

X = 60

cost of 12 articles is 60rs.

assuming all the prices are same

he will get 18 articles for 90rs.
