Answer 2

Find the cost of the rice :

20 kg at 36 per kg = 20 x 36 = Rs 720

25 kg at 32 per kg = 25 x 32 = Rs 800

Total = 720 + 800 = Rs 1520

Find the selling price:

Total kg = 20 + 25 = 45 kg

55 kg at 38 per kg = 45 x 38 = Rs 1710

Find the Gain:

Gain = Selling Price - Cost Price

Gain = 1710 - 1520 = Rs 190

Find the Gain percentage:

Gain percentage = gain/cost price  x 100

Gain percentage = 190/1520 x 100 = 12.5%

Answer: There is a gain of 12.5% for this transaction.
