Question

A person bought some articles at the rate of 5 per rupee (₹) and the same number of articles at the rate of 4 per rupee (₹). He mixed both the types and sold them at the rate of 9 for ₹2. In this business, he suffered a loss of ₹3. The total number of articles bought by him was:

a. 1090

b. 1080

c. 540

d. 545

Answer 1

• B. 1080

Explanation:

Lets assume the number of articles was x.

Half of the articles was bought at the price 1/5 rupee each and the other half was bought at the price 1/4 rupee each.

Cost of articles:

• 1/2x*1/5 + 1/2x*1/4 =
• 1/2x(1/5 + 1/4) =
• 1/2x(4/20 + 5/20) =
• 9/40x

Money made after sale is:

• 2/9x according to rate

The difference is 3 rupees:

• 9/40x - 2/9x = 3
• 81/360x - 80/360x = 3
• 1/360x = 3
• x = 3*360
• x = 1080

Correct choice is B
