1.	The cost price of an article A is 20% more than that of B. A is sold for Rs. 1,800 at a loss of 20% and B is sold such that there is a profit of 20% on both A and B together. The selling price of B is:1. Rs. 3,1502. Rs. 2,9803. Rs. 3,1204. Rs. 2,940
Answer» Correct Answer - Option 1 : Rs. 3,150 Given: The cost price of the article A is 20% more than that of B. A is sold for Rs. 1,800 at a loss of 20% Calculation: Let cost price of B be Rs.a. Cost price of A = Rs.120a/100 A is sold for Rs. 1,800 at a loss of 20% ⇒ Cost price of A is 1800 × 100/80 Accordingly, 120a/100 = 1800 × 100/80 ⇒ a = Rs.1875 Cost price of A = 1875 × 120/100 = Rs.2250 Total cost price of A and B = 2250 + 1875 = Rs.4125 Total selling price = 4125 × 120/100 = Rs.4950 ∴ Selling price of B = 4950 - 1800 = Rs.3150

The cost price of an article A is 20% more than that of B. A is sold for Rs. 1,800 at a loss of 20% and B is sold such that there is a profit of 20% on both A and B together. The selling price of B is:1. Rs. 3,1502. Rs. 2,9803. Rs. 3,1204. Rs. 2,940

Answer» Correct Answer - Option 1 : Rs. 3,150

Given:

The cost price of the article A is 20% more than that of B.

A is sold for Rs. 1,800 at a loss of 20%

Calculation:

Let cost price of B be Rs.a.

Cost price of A = Rs.120a/100

A is sold for Rs. 1,800 at a loss of 20%

⇒ Cost price of A is 1800 × 100/80

Accordingly,

120a/100 = 1800 × 100/80

⇒ a = Rs.1875

Cost price of A = 1875 × 120/100 = Rs.2250

Total cost price of A and B = 2250 + 1875 = Rs.4125

Total selling price = 4125 × 120/100 = Rs.4950

∴ Selling price of B = 4950 - 1800 = Rs.3150
