Question

A man sells his two articles at Rs1200. At one he gains 25% and at another he gains 16(2/3)%. Overall he gains 20%. Find the cost price of first article?

Answer 1

Let the cost price of first article be $C$

Then cost price of second article = $1200-C$

According to question , $C\times \frac{5}{4}+($ $1200-c$)($\frac{116.66}{100}$=$1200\times \frac{6}{5}$

Solving we get $C=480$
