A. Rs.22400
B. Rs.25200
C. Rs.23520
D. Rs.24000

21. The percentage profit earned by selling an article for Rs.1920 is equal to the percentage loss incurred by selling the same article for Rs.1280. At what price should the article be sold to make 25% profit?
A. Rs. 2000
B. Rs. 2200
C. Rs. 2400
D. Data inadequate
Answer
Explanation:
Let C.P. be Rs.x.
Then, [(1920 – x)/x] * 100 =[(x – 1280)/x] * 100
or, 1920 – x = x – 1280
or, 2x = 3200
So, x = 1600
Required S.P. = 125% of Rs. 1600
=( Rs.125/100)x 1600 = Rs.2000.
22. A shopkeeper sells his goods at the cost price but uses a false weight of 950 gm. Find his gain %.
A. 5%
B. 5(5/19)%
C. 4(5/19)%
D. 5(10/19)%
Answer
Explanation:
Let the cost of 1 kg of goods be Rs.100.
The cost of 950g is Rs. 95.
He sells Rs.95 worth goods for Rs.100.
Gain = Rs.5 C.P = Rs.95
Gain % = (5/95) * 100 = 5(5/19)%.
23. A shopkeeper sells 1 kg of apples for Rs. 160 at a loss of 20%. At what price should he sell a kg of apples to gain 20%?
A. Rs.200
B. Rs.220
C. Rs.240
D. Rs.250
Answer
Explanation:
Let the cost price be Rs.(160+x)
Loss = Rs.x
Loss% = (x/(160+x))*100 = 20%
x = Rs.40
C.P=Rs.200
Gain% = (Gain/C.P) * 100 = 20%
Gain = Rs.40
S.P=Gain + C.P=Rs.240
24. The SP of 4 articles equals the CP of 6 articles. Find the gain%.
A. 40%
B. 50%
C. 25%
D. 20%
Answer
Explanation:
Let the CP of an article be Rs.x.
4*SP=6x SP
= 6x/4 = 3x/2
Gain = (3x/2)-x = x/2
Gain % = (x/2)/x *100 = 50%
25. Gopal purchased 35 kg of rice at the rate of Rs 9.50 per kg and 30 kg at the rate of Rs 100 per kg. He mixed the two. Approximately, at what price per kg should he sell the mixture to make 35 % profit in the transaction?
A. Rs 12
B. Rs 13
C. Rs 12.50
D. Rs 13.50
Answer
Explanation:
Cost Price of 65 kg rice = Rs. (35 x 9.50 + 30 x 10.50)
= 647.50
Sell Price of 65 kg rice = 135 % of 647.50
= Rs (135/100) x 647.50
Sell Price per kg = (135/100) x 647.50 x (1/65)
= 13.44
= Rs. 13.50 (Approx)

Total cost = Rs.12000 = Total S.P i.e. neither gain nor loss.
