Answer» Correct Answer - Option 1 : C Given: Selling price = Rs. 910 And profit = 30% Another Selling price = Rs. 180 And loss = 10% Formula used: Profit = Cost price – Selling price Profit% = (Profit × 100)/Cost price Cost price = [{100/(100 + profit %)} × Selling price] Cost price = [{100/(100 – loss %)} × Selling price] Calculation: According to the question: ⇒ CP of first Pen drive = [{100/(100 + 30%)} × 910 ⇒ CP = [(100/130) × 910] ⇒ CP = Rs. 700 Again, ⇒ CP of second Pen drive = [{100/(100 – 10%)} × 180 ⇒ CP = [(100/90) × 180] ⇒ CP = Rs. 200 Total CP = (700 + 200) = Rs. 900 Total SP = (910 + 180) = Rs. 1090 Profit = (1090 – 900) = Rs. 190 Profit % = (190/900) × 100 ⇒ 19/9 = 21.11% ∴ Total profit is 21.11%.

Answer» Correct Answer - Option 1 : C

Given:

Selling price = Rs. 910

And profit = 30%

Another Selling price = Rs. 180

And loss = 10%

Formula used:

Profit = Cost price – Selling price

Profit% = (Profit × 100)/Cost price

Cost price = [{100/(100 + profit %)} × Selling price]

Cost price = [{100/(100 – loss %)} × Selling price]

Calculation:

According to the question:

⇒ CP of first Pen drive = [{100/(100 + 30%)} × 910

⇒ CP = [(100/130) × 910]

⇒ CP = Rs. 700

Again,

⇒ CP of second Pen drive = [{100/(100 – 10%)} × 180

⇒ CP = [(100/90) × 180]

⇒ CP = Rs. 200

Total CP = (700 + 200) = Rs. 900

Total SP = (910 + 180) = Rs. 1090

Profit = (1090 – 900) = Rs. 190

Profit % = (190/900) × 100

⇒ 19/9 = 21.11%

∴ Total profit is 21.11%.
