Question

a person bought 16 articles for rs 25 and sold 5 articles for rs 12 so overall he gains rs 134. find the number of articles he bought?

Answer 1

The number of articles the person bought is 160.

Step-by-step explanation:

The cost price of 16 articles = Rs. 25

So, the C.P. of 1 article = $\frac{25}{16}$ = Rs. 1.5625

The selling price of 5 articles = Rs. 12

So, the S.P. of 1 article = $\frac{12}{5}$ = Rs. 2.4

∴ Profit earned from 1 article = Rs. 2.4 - Rs. 1.5625 = Rs. 0.8375

The overall profit earned by the person in the transaction is Rs. 134

Thus,

The number of articles that the person bought is,

= [Total profit earned] / [Profit earned from 1 article]

= $\frac{134}{0.8375}$

= 160
