Question

A dealer bought 80 cricket bats for rupees 50 each he sold 10% of bats at the rate of rupees 40 and remaining bats at the rate of rupees 50 each find his loss percent

Answer 1

bought price of bat = 80 × 50 = 4000
10% bat sold at 40 Rupees = 80 10 % = 8 bat
8 bat at 40 = 40× 8 = 320
remains bat at 50 = 80 - 8 = 72 × 50 = 3600
3600 + 320 = 3920
loss = 4000 -3920 = 80
$\frac{80}{4000} \times \frac{x}{100} \: \frac{8000}{4000}$
= the dealer have loss of 2%
