1
33.3%. Find the number of articles bought
by the man for 90.​

Answer 1

Answer:

18

Step-by-step explanation:

Let, the cost price will be x.

selling price = x + profit

profit = 33.3% of x = x/3

Therefore, selling price = x + x/3 = 80

4x/3 = 80

Therefore, x = 60

Cost of 12 articles = Rs 60

Cost of 1 article = Rs 5

Let the number of articles bought by man for Rs 90 be y and cost of one article is Rs 5.

5y = 90

y = 18

Therefore, number of articles = 18
