Answer 1

Answer:

11.04%

Step-by-step explanation:

50 × 90 = 4500rs

40 × 80 = 3200rs

Total amount spent = 7700rs

Total kg = 90kg

Sold for 95× 90 = 8550rs

Now find % gain

8550-7700 = 850

850/7700 × 100 = 11.04%

Hope it's correct

Answer 2

Answer:

50×90=4500 rs.

40×80=3200 rs.

total = 7700 rs.

he mixed the both oil,

so total oil = 90 kg.

sold at 95 rs / kg

selling price = 90×95= 8550

profit = sp- cp = 8550 - 7700= 850 rs.

profit (%) = 850÷7700×100= 11.03% of profit

profit = 11.03%
