6. A man buys two pens at Rs20 each. He sells one at a gain of 5% and other at a loss of 5%. Find his gain or loss per cent.
Answers
Cost Price of lst pen = ₹20
Gain = 5% of ₹20
= 5/100 × ₹20
= ₹1
Selling Price = Cost Price + Gain
= ₹(20+1)
= ₹21
Cost Price of 2nd pen = ₹20
Loss = 5% of ₹20
= 5/100 × ₹20
= ₹1
Selling Price = Cost Price - Loss
= ₹(20-1)
= ₹19
Total cost price of both pens =₹(20×2) = ₹40
Total selling price of both pens = ₹(21+19) = ₹40
Cost Price = Selling Price.
So, there is no gain no loss.
Hence, no gain % no loss %.
