A man sold an article at loss of 20%. If he sells the article for ₹ 12 more, he would have gained 10%. The cost of price of the article is ?
-
- ₹ 60
- ₹ 40
- ₹ 30
- ₹ 22
Correct Option: B
Let the CP = N
According to the question, (110N/100) - (80N/100) = 12
⇒ (11N/10) - (4N/5) = 12
⇒ 11N - 8N = 120
∴ N = 120/3 = 40
∴ CP = ₹ 40
