A person bought some articles at the rate of 5 per rupee and the same number at the rate of 4 per rupee. He mixed both the types and sold at the rate of 9 for 2 rupees. In this business he suffered a loss of ₹ 3. The total number of articles bought by him was
(a)540
(b)545
(c)1080
(d)1090
Answer
Answer (as printed): C
Explanation
Suppose number of articles bought of each kind = L.C.M. of 5, 4, 9 = 180. $$\text { C.P. of } 360 \text { articles }=₹\left(\frac{1}{5} \times 180+\frac{1}{4} \times 180\right)=₹ 81 .$$ S.P. of 360 articles $=₹\left(\frac{2}{9} \times 360\right)=₹ 80$. If loss is ₹ 1, articles bought = 360. If loss is ₹ 3 , articles bought $=(360 \times 3)=1080$.
