Answer» Correct Answer - Option 4 : 6000 Given: Difference between their profits = 200 Profit gain by Mahesh and Dinesh both = 20% Formula used: Gain or loss percent = (Loss or gain/Cost price) × 100 Concept used: Profit = Selling Price – Cost Price Loss = Cost Price – Selling Price Calculation: Let the selling price for both of them be Rs. x. Cost price of Dinesh = x × {(100 - 20)/100} ⇒ x × {80/100} ⇒ 4x/5 Cost price of Mahesh = x × {100/(100 +20)} ⇒ x × {100/120} ⇒ 5x/6 Dinesh’s profit = x – (4x/5) ⇒ x/5 Mahesh’s profit = x – (5x/6) ⇒ x/6 Difference of their profits = (x/5) – (x/6) = 200 ⇒ x/30 = 200 ⇒ x = 6000 ∴ The selling price for both of them is Rs. 6000.

Answer» Correct Answer - Option 4 : 6000

Given:

Difference between their profits = 200

Profit gain by Mahesh and Dinesh both = 20%

Formula used:

Gain or loss percent = (Loss or gain/Cost price) × 100

Concept used:

Profit = Selling Price – Cost Price

Loss = Cost Price – Selling Price

Calculation:

Let the selling price for both of them be Rs. x.

Cost price of Dinesh = x × {(100 - 20)/100}

⇒ x × {80/100}

⇒ 4x/5

Cost price of Mahesh = x × {100/(100 +20)}

⇒ x × {100/120}

⇒ 5x/6

Dinesh’s profit = x – (4x/5)

⇒ x/5

Mahesh’s profit = x – (5x/6)

⇒ x/6

Difference of their profits = (x/5) – (x/6) = 200

⇒ x/30 = 200

⇒ x = 6000

∴ The selling price for both of them is Rs. 6000.
