The cost price of 36 articles is the same as the selling price of N articles. If the profit is 20%, then the value of N is:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 30.
Given that
The C.P of 36 articles = S.P on N articles
Profit gained = 20%
Selling price = Cost price × (100 + profit %)/100
Let the C.P of 1 article = 1
S.P = × 1 = 1.2
According to the question
36 = 1.2 × N
Hence, N = 30
Hence, the value of N is 30.
