A shopkeeper sold two baseball bats whose cost price is ₹2000 each. If he makes a profit of 15% on one bat and a loss of 5% on the other bat, then find the overall gain or loss.
Profit of 5%
When cost price is the same, a profit of 15% and loss of 5% will always give an overall profit.
Cost price of each bat = ₹2000
Total cost price of two bats (C.P)
= ₹2000 + ₹2000 = ₹4000
Profit = 15 % of cost price
= 15100×2000
= ₹300
Loss = 5 % of cost price
= 5100×2000
= ₹100
Total selling price (S.P)
= (2000 + 300) + (2000 - 100)
= ₹2300 + ₹1900
= ₹4200
So, SP > CP.
∴ Profit = ₹4200 - ₹4000 = ₹200
Profit percentage = 2004000×100 = 5%
