Question

a dealer bought 100 quintal of rice at rs700 per quintal. he sold 50 quintal at rs 1000 per quintal and the remaining at rs 800 per quintal. find his gain and gain percent.

Answer 1

sold price = 1000×50 + 50×800
= 50× 1800
= 90000

bought at = 700×100 = 70000

gain= 90000-70000 = 20000

gain% = 20000/70000 ×100
= 200/7%

Answer 2

Find the cost price:

1 quintal = Rs 700

100 quintal = 700 x 100 = Rs70,000

Find the selling price of 50 quintal:

1 quintal = Rs 1000

50 quintal = 50 x 1000 = Rs 50,000

Find the remaining amount of quintal:

Remaining amount = 100 - 50 = 50 quintal

Find the selling price of the remaining quintal:

1 quintal = Rs 800

50 quintal = 800 x 50 = Rs 40,000

Find the total selling price:

Total = 50,000 + 40,000 = Rs 90,000

Find the gain:

Gain = Selling Price - Cost Price

Gain = 90,000 - 70,000 = Rs 20,000

Gain percentage = gain / cost price x 100

Gain percentage = 20,000/70,000 x 100 = 28.57%

Answer: The gain is Rs 20,000 and it is 28.57%
