- D. 12
- Correct Answer
- 12
ExplanationLet quantities of two types of tea costing ? 18 per kg and ? 20 per kg be 5W kg and 3W kg. respectively.
Then, CP of tea = (18 x 5W) + (20 x 3W)
= 90W + 60W = 150W
SP of tea = 21 x 8W = 168W
Profit percent = [(168W - 150W) / 150W] x 100%
= (18/150) x 100% = 12% - 1. Kamlesh purchased 120 reams of paper at ? 100 per ream and the expenditure on transport was ? 480. He had to pay an octroi duty of 50 paise per ream and the coolie charges were ? 60. What should he charge per ream to gain 40%?

Correct Answer: ? 147
Explanation:
Total cost price = ? (120 x 100) = ? 12000
Total expenditure = 480 + (1/2) x 120 + 60 = ? 600
Total cost price = 12000 + 600 = ? 126000
Gain = 40%
SP of 120 reams = 12600 x (140/100) = ? 17640
? SP per ream = 17640/120 = ? 147
Correct Answer: 24
Explanation:
Let the cost price be ? N.
SP of 1 orange = ? 30/32 = ? 15/16
According to the question, 75N/100 = 15/16
? N = [(15 x 100)/75] x 16 = ? 5/4
SP of 1 orange with 20% profit = ? [(5/4) x 120]/100 = ? 3/2
? In ? 3/2, the number of oranges sold = 1
? in ? 24, the number of oranges sold = (2/3) x 24 = 16
Correct Answer: ? 24
Explanation:
SP of 1 lemon = ? 14/5
Let CP of 1 lemon = N
According to the question, (N x 140)/100 = 14/5
? N = ? 2
? CP for 12 lemons = 12 x 2 = 24
Correct Answer: 20% profit
Explanation:
Let each lot of onion-contain N kg onion,
Then total cost price of these two lots together = 10N + 15N = 25N
Selling price of whole lot = 15 x (N + N) = 15 x 2N = 30N
Profit percentage = [(30N - 25N)/25N] x 100 %
= (5/25) x 100%
= 20%
Correct Answer: ? 50
Explanation:
Let CP of the watch be ? N.
Then , According to the question,
[(75 - N)/ N] x 100 = N
? (75 - N) x 100 = N2
? N2 + 100N - 7500 = 0
? N2 + 150N - 50N - 7500 = 0
? N(N + 150) - 50 (N + 150) = 0
? (N + 150) (N - 50) = 0
? N = ? 50
Correct Answer: 56.26%
Explanation:
Let the number of pens bought = 5 x 4 = 20
Then, CP = (4/5) x 20 = ? 16
and SP = (5/4) x 20 = ? 25
? Gain = 25 - 16 = ? 9
Gain % = (9/16) x 100% = 56.25%
Correct Answer: 21
Explanation:
Cost price of 11 Articles = 10
Cost price of 1 Article = 10/11
and SP of 10 Articles = 11
? SP of 1 Article = 11/10
Now, gain = (11/10) - (10//11)
= (121 - 100)/110 = 21/110
And gain% = [(21/110) / (10/11)] x 100
= (21 x 11)/11 = 21
Correct Answer:
Explanation:
(SP of 100 pens) - (CP of 100 pens) = SP of 40 pens
? SP of 60 pens = CP of 100 pens.
Let CP of each pen = ? 1
Then, CP of 60 pens = ? 60
SP of 60 pens = ? 100
Gain = 100 - 60 = ? 40
? Gain % = (40/60) x 100 % = 66.67%
Correct Answer: 331/3%
Explanation:
Here, a = 16, b = 12
According to the formula,
Required gain percent = [(a - b)/b] x 100
= [(16 - 12)/12] x 100
= (4/12) x 100
= 331/3% (gain)
Correct Answer: 12.5% gain
Explanation:
Here, a = 10% and b = 20%
According to the formula,
Required answer= [b ± a/(100 - b)] x 100 %
= (20 - 10)/(100 - 20 ) x 100%
= (10/80) x 100% = 12.5 % gain
+ ve sign show that profit is earned here.
