Problems on Profit and Loss : Question 1 :
The cost price of three varieties of oranges namely A, B and C is Rs 20/kg, Rs 40/kg and Rs 50/kg. Find the selling price of one kg of orange in which these three varieties of oranges are mixed in the ratio of 2 : 3 : 5 such that there is a net profit of 20%?
Rs 48
Rs 48.6
Rs 49.2
Rs 49.8
Show Answer
Explanation:
Cost price of one kg of orange in which the three varieties of oranges are mixed in the ratio 2 : 3 : 5 is equal to S where
S = 0.2 x 20 + 0.3 x 40 + 0.5 × 50
= 4 + 12 + 25
= Rs 41
Selling price per kg of oranges to ensure there is a net profit of 20%
= 1.2 x 41
= Rs 49.2
Problems on Profit and Loss : Question 2 :
A sweet seller sells 3/5th part of sweets at a profit of 10% and remaining at a loss of 5%. If the total profit is Rs 1500, then what is the total cost price of sweets?
Rs 36,500
Rs 37,000
Rs 37,500
None of these
Show Answer
Explanation:
Assume A be the cost price.
Therefore,
[{(3/5) x A x (10/100)} – {(2/5) x A x 5/100}] = 1500
Or A = Rs 37,500
Problems on Profit and Loss : Question 3 :
’A’ sold an article to ’B’ at a profit of 20%. ’B’ sold the same article to ’C’ at a loss of 25% and ’C’ sold the same article to ’D’ at a profit of 40%. If ’D’ paid Rs 252 for the article, then find how much did ’A’ pay for it?
Rs 175
Rs 200
Rs 180
Rs 210
Show Answer
Explanation:

Let the article costs ‘X’ to A
Cost price of B = 1.2X
Cost price of C = 0.75(1.2X) = 0.9X
Cost price of D = 1.4(0.9X) = 1.26X = 252
Amount paid by A for the article = Rs 200
Problems on Profit and Loss : Question 4 :
If the absolute difference between the selling price of the article when there is 15% loss and 15% gain in selling a article is Rs 450, then what is the cost price of the article?
Rs 1,200
Rs 1,500
Rs 2,000
Rs 2,200
Show Answer
Explanation:
If C.P. = Rs 100
Given, 115% of C.P - 85% of C.P = Rs 30
When C.P. = Rs ’X’
115% of C.P - 85% of C.P = Rs 450
Therefore, X = 450/30 x 100
Problems on Profit and Loss : Question 5 :
On selling an article at successive discounts of 20% and 25% a dealer makes a net profit of 20%, Find the net profit per cent if the dealer sells the same article at a discount of 25%.
50%
40%
66%
60%
Show Answer
Explanation:
Let the cost price and market price of the article be ’x’ and ’y’ respectively.
Case 1: Successive discounts of 20% and 25%
Selling price of a the article = (0.8)(0.75)(y) = 0.6y
Therefore, 0.6y = 1.2x or, y = 2x
Case 2: A single discount of 25%
Selling price of the article = 0.75y = 1.5x
Net profit per cent = [(1.5x - x)/x] 100 = 50%
