A fruit seller sold 50 kg of orange at the rate of rupees 80 per kg and gained rupees 800 calculate his purchasing rate.

Lorico [155]

Step-by-step explanation:

selling price of 1 kg oranges = rupees 80

so, selling price of 50 kg oranges :-

=》80 × 50

=》4000

now, profit = 800

so, Cost price (C.P) = selling price - profit

=》C.P = 4000 - 800

=》C.P = 3200

SO, purchasing rate per kg was

=》3200 ÷ 50 = 64

hence, purchasing rate = 64 rupees per kg

profit % =

$\frac{profit}{cost \: price} \times 100$

=》

$\frac{800}{3200} \times 100$

=》

$\frac{1}{4} \times 100$

=》

$25$

hence, profit % = 25%
