Answer 1

Given data:

Selling price of each pen: Rs. 12

Gain on first pen: 20%

Loss on second pen: 20%

Concept:

Cost Price = 100 × SP/(100 ± Profit%/Loss%)

Loss = CP - SP

Calculation:

SP of each pen = Rs. 12

Gain on first pen: 20%

⇒ CP₁ = 100 × 12/(100 + 20)

⇒ CP1 = Rs. 10

Loss on second pen: 20%

⇒ CP2 = 100 × 12/(100 - 20)

⇒ CP2 = Rs. 15

⇒ Total CP = 10 + 15 = Rs. 25

⇒ Total SP = 12 + 12 = Rs.24

Loss = CP - SP

⇒ 25 - 24 = Rs. 1

Therefore, On the whole, he lost Rs. 1.
