question :

Amit bought 20 liters of oil at the rate of 75 rs/liter and the same amount of oil at the rate of 115 rs/liter and mixed them. If he sold the mixture at 100 rs/liter. Find his total profit?

answer:

amount of total oil bought

=20 l + 20 l

cost of total oil bought

$= 20 \times 75 + 20 \times 115 \\ = 1500 + 2300 \\ = 3800$

amount of total oil sold

=20l + 20l

=40 l

cost of total oil sold

$= 40 \times 100 \\ = 4000$

profit = SP - CP = ₹4000-3800

= ₹200
