Question

plzz help me its the question of percentage chapter i am from class 8 plzz help

Answer 1

bought wheat cost =35000
$\frac{1}{7} \: wheat \: spoiled = 35000 \times \frac{1}{7} \\ = 5000$
cost of good wheat
whole wheat - spoiled wheat
$35000 - 5000 = 30000$
ATQ
He sold good wheat on 10% gain .
$30000 + 10\% = 30000 + \frac{10}{100} \times 30000 \\ 30000 + 3000 = 33000$
and sold the spoiled wheat on 25% loss.
$5000 - 25\% = 5000 - \frac{25}{100} \times 5000 \\ 5000 - 1250 = 3750$
sold price of whole wheat
$33000 + 3750 = 36750$
Profit =S.P - C.P
$36750 - 35000 = 1750$
profit% =
$\frac{total \: profit}{c.p} \times 100 = \frac{1750}{35000} \times 100 \\ \frac{1750}{350} = \frac{250}{50} = 5\% \: ans$
