- 35%
- 31.6%
- 32%
- 36.7%
Solution
(1
– 0.2) (1 – 0.1) (1 – 0.05)
– 0.2) (1 – 0.1) (1 – 0.05)
=
0.8 x 0.9 x 0.95 = 0.684 = (1 – 0.316)
0.8 x 0.9 x 0.95 = 0.684 = (1 – 0.316)
Q2.If a commission of 10% is given on the marked price of a article, the gain is 25%. Find the gain percent, if the commission is increased to 20%.
- 1%
- 2%
- 3%
- 11%
Solution
Let
the Marked price be Rs 100
the Marked price be Rs 100
Then
SP = Rs (90/100) x 100 = Rs 90
SP = Rs (90/100) x 100 = Rs 90
Gain
= 25%.
= 25%.
CP
= (100/125) x 90 = Rs 72
= (100/125) x 90 = Rs 72
New
Commission = Rs 20, New SP = Rs 80
Commission = Rs 20, New SP = Rs 80
New
Profit = (8/72) x 100 = Rs 11
%
Profit = (8/72) x 100 = Rs 11
%
Q3.If a commission of 10% is given on the marked price of a article, the gain is 25%. Find the gain percent, if the commission is increased to 20%.
- 1%
- 2%
- 3%
- 4%
Solution
SP
= (1 + 0.2)(1 – 0.15)CP = 1.2 x 0.85CP – 1.02CP
= (1 + 0.2)(1 – 0.15)CP = 1.2 x 0.85CP – 1.02CP
Q4.Two-third of a consignment was sold at a profit of 5% and the remainder at loss of 2%. If the profit was Rs 400, the value of consignment was.
- 20000
- 15000
- 12000
- 10000
Solution
P
= 2/3(5%) + 1/3(-2%) = 8/3% CP = 400
= 2/3(5%) + 1/3(-2%) = 8/3% CP = 400
CP
= 400×300/8 = 15,000
Q5.A man sells two commodities at the same price. On one he gains 20% and loses 20% on the other, He gets:
- 1% loss
- 4% loss
- 1% gain
- no gain no loss
Solution
SP
= 1.2CP1
= 0.8 CP2
= 1.2CP1
= 0.8 CP2
CP1
+ CP2
=
= SP
SP
+ CP2
=
= SP
SP
= Since
2 items 2SP = 0.96 (CP1
+ CP2)
2 items 2SP = 0.96 (CP1
+ CP2)
=
(1- 0.04)(CP1
+ CP2)
(1- 0.04)(CP1
+ CP2)

Q7.A man loses Rs 20 by selling some toys at the rate of Rs 3 per piece and gains Rs 30, if he sells them at Rs 3.25 per piece. The number of pieces sold, by him is:
- 100
- 120
- 200
- 300
Solution
Let
price = P Quantity = Q
price = P Quantity = Q
PQ
– 3Q = 20, PQ – 3.25Q = -30
– 3Q = 20, PQ – 3.25Q = -30
therefore Q
= 200
= 200
Q8.On selling an article for Rs 240, a trader loses 4%. In order to gain 10%, he must sell that article for :
- Rs 264
- Rs 273.20
- Rs 275
- Rs 280
Solution
(1.00
– 0.04) = 240 , CP
– 0.04) = 240 , CP
1.1
CP = 1.1 x 240/0.96 = 275
CP = 1.1 x 240/0.96 = 275
Q9.A man bought an article and sold it at a gain of 6%. If he had bought it at 5% less and sold it for Re 1 less, he would have made a profit of 10%. The CP of the article was:
- Rs 100
- Rs 150
- Rs 67
- Rs 500
Solution 
1.06CP
– 1 = 1.045CP
Initial
SP = 1.06 CP
SP = 1.06 CP
New
SP = Old SP – 1 = (0.95)CP x (1.1) = 1.045CP
SP = Old SP – 1 = (0.95)CP x (1.1) = 1.045CP
1.06CP– 1 = 1.045CP
= 0.015CP
= 1 ,
CP = 66.66
= 1 ,
CP = 66.66
Q10.A reduction of 25% in the price of eggs will enable one to buy 4 dozen more eggs for Rs 96. What is the price per dozen?
- Rs 6
- Rs 8
- Rs 8.50
- Rs 9
Solution
Let
Price be P & Quantity be Q
Price be P & Quantity be Q
PQ
= 0.75P (Q + 4) = 96 …………..(i)
= 0.75P (Q + 4) = 96 …………..(i)
96
= 3P + 72
= 3P + 72
P = 8 Q = 12
