If the selling price of an article is Rs. 342 and the profit is 14%, find the cost price. MCQ with Answer and Explanation

Explanation:
When two articles are sold at the same price, and one is sold at a gain of x% and the other at a loss of x%, there is always an overall loss. Loss percentage = (x^2) / 100 = (20^2) / 100 = 400 / 100 = 4% Loss.

Explanation:
Gain = 30, gain% = 30/150*100 = 20%.

Explanation:
Loss = 800, loss% = 800/8000*100 = 10%.
