5%. Find his gain or loss per cent.
​

Answer 1

Given:-

• CP of both pens = ₹20

To find:-

• Gain/Loss %

__________________________________

Solution:-

For the first pen,

• CP = ₹20
• Gain% = 5%

∴ SP = ₹20+ (5% of 20) = ₹21

For the second pen,

• CP = ₹20
• Loss% = 5%

∴ SP = ₹20 -(5%of 20) = ₹19

__________________________________

Total CP = ₹20+₹20 = ₹40

Total SP = ₹21+₹19 = ₹40

Hence, at the end , his gain/loss is 0%
