Correct Answer - Option 3 : Rs. 341.25

**Given:**

A is sold at 20% profit, B is sold for Rs. 54.60 more than the selling price of A

The overall profit earned on selling A and B is 28%

**Formula used:**

Profit = Selling price – Cost price

SP = [(100 + profit %)/100 × CP]

**Calculation:**

Let C.P of A nd B be Rs. x

According to the question:

S.P of A = (x × 120/100) = 6x/5

S.P of B = (6x/5 + 54.60)

Total C.P = Rs. (x + x) = Rs. 2x

Total S.P = (6x/5 + 54.60 + 6x/5)

⇒ (12x/5 + 54.60)

Profit = (12x/5 + 54.60 – 2x)

⇒ 2x/5 + 54.60

Now,

⇒ 28% of 2x = 2x/5 + 54.60

⇒ [(28/100) × 2x] = 2x/5 + 54.60

⇒ [(28/100) × 2x] = [2x/5 + (5460/100)]

⇒ [(28/100) × 2x] = (4x + 546)/10

⇒ 28x = 20x + 2730

⇒ 8x = 2730

⇒ x = 2730/8 = Rs. 341.25

**∴The cost price of each article is Rs. 341.25.**
