Manjit bought an iron safe for 12160 and paid 340 for its transportation. Then, he sold it for 12875. Find his gain per cent
Solution:
CP of the iron safe = 12,160
Money spent on transportation = 340
Total CP = 12,160 + 340 = 12,500
SP of the iron safe = 12,875

Robin purchased an old car for Rs 73500. He spent Rs 10300 on repairs and paid Rs 2600 for its insurance. Then he sold it to a mechanic for Rs 84240. What was his percentage gain or
loss?
Solution:
CP of the car = Rs. 73500Repairs = Rs. 10300Insurance = Rs. 2600Total CP = 73500 +10300 +2600 = Rs. 86400SP = Rs. 84240Since SP < CP, Robin has a loss. Loss = 86400 -84240
Question:6
Hari bought 20 kg of rice at 36 per kg and 25 kg of rice at 32 per kg. He mixed the two varieties and sold the mixture at 38 per kg. Find his gain per cent in the whole transaction.
Solution:
Total cost of rice of 1st variety = 36/kg × 20 kg = 720
Total cost of rice of 2nd variety = 32/kg × 25 kg = 800
Total cost of the two rice varieties = 720 + 800 = 1,520
Total quantity of the two rice varieties = 20 kg + 25 kg = 45 kg
Selling price of the mixture of two rice = 38/kg × 45 kg = 1,710

Question:7
Coffee costing Rs 250 per kg was mixed with chicory costing Rs 75 per kg in the ratio 5 : 2 for a certain blend. If the mixture was sold at Rs 230 per kg, find the gain or loss per cent.
Solution:
Let 5 kg of coffee be mixed with 2 kg of chicory. CP of the mixture = Rs 250 ×5 +75 ×2 = Rs 1250 +150 = Rs. 1400SP of the mixture = Rs 7 ×230 = Rs. 1610Since SP > CP, there
Question:8

Question:21
Sonu buys 40 kg of wheat at 12.50 per kg and 30 kg of wheat at 14 per kg. At what rate per kg should he sell the mixture to gain 5% on the whole?
Solution:
40 kg of wheat is bought for 12.50/kg.
? CP of 40 kg of wheat = 40 × 12.50 = 500
30 kg of wheat is bought for 14/kg.
? CP of 30 kg of wheat = 30 × 14 = 420
Total CP = 500 + 420 = 920
Profit = 5% of CP = 5% of 920 =

×920 = 46
Let the SP be x.

Thus, the selling price of the mixture is 13.80/kg.
Question:22
Wasim bought two cricket bats for 840 and 360 respectively. He sells the first bat at a gain of 15% and the second one at a loss of 5%. Find his gain or loss per cent in the whole
transaction.
Solution:
CP of the first bat = 840
Profit% on the first bat = 15%
? Profit = 15% of 840 =
15
100
×840 = 126
SP of the first bat = 840 + 126 = 966
CP of the second bat = 360
Loss = 5% of 360 =

100
×360 = 18
SP of the second bat = 360 - 18 = 342
Total CP of two bats = CP of first bat + CP of second bat = 840 + 360 = 1,200
Total SP of two bats = SP of first bat + SP of second bat = 966 + 342 = 1,308
Here, Total SP of two bats > Total CP of two bats.
Gain = Total SP of two bats - Total CP of two bats = 1,308 - 1,200 = 108

100
×1450 = 58
SP of second jeans = 1450 - 58 = 1,392
Total CP of two jeans = CP of first jeans + CP of second jeans = 1,450 + 1,450 = 2,900
Total SP of two jeans = SP of first jeans + SP of second jeans = 1,566 + 1,392 = 2,958
Here, Total SP of two jeans > Total CP of two jeans.
Gain = Total SP of two jeans - Total CP of two jeans = 2,958 - 2,900 = 58

Question:24
A grocer purchased 200 kg of rice at Rs 25 per kg. He sold 80 kg of it at a gain of 10% and 40 kg at a loss of 4%. At what rate per kg should he sell the remainder to gain 8% on his total
investment?
Solution:
CP of 1 kg of rice = Rs 25
C.P of 200 kg rice= Rs (200 ×25) = Rs 5000
CP of 80 kg of rice=Rs (25 ×80) = Rs 2000
CP of 40 kg of rice = Rs (25 ×40) = Rs 1000
SP of 80 kg of rice =
100+gain%
100
×CP = Rs
