Question

A trader bought a number of articles for Rs. 1,200. Ten were damaged and he sold each of the remaining articles at Rs. 2 more than what he paid for it, thus getting a profit of Rs. 60 on the whole transaction ?

Taking the number of articles he bought as x, form an equation in x and solve it.

Answer 1

Number of articles bought by the trader = x
It is given that the trader bought the articles for Rs 1200.

Number of articles cannot be negative. So, x = 100.
