A. 50
B. 100
C. 150
D. 200

1(B)Explanation:
A : B = 2 : 3
B : C = 4 : 5 = (4*3/4 : 5*3/4)
=3 : 15/4
C:D=6:7=(6*15/24:7*15/24)
=15/4 : 35/8
A : B : C : D = 2 : 3 : 15/4 : 35/8
= 16 : 24 : 30 : 35

2(C)Explanation:
Let the shares of A, B, C and D be Rs. 5x, Rs. 2x, Rs. 4x and Rs. 3x respectively.
Then, 4x - 3x = 1000
x = 1000.
B's share = Rs. 2x = Rs. (2 x 1000) = Rs. 2000.

3(D)Explanation:
Let A salary be 2k
B salary be 3k and C salary be 5k
A's new salary = 115/100*2k
=23/10k
B's new salary = 110/100*3k
=33/10k
C's new salary = 120/100*5k
=6k
New ratio = 23k/10 : 33k/10 : 6k
= 23 : 33 : 60

4(A)Explanation:
Originally, let the number of seats for Mathematics, Physics and Biology be 5x, 7x and 8x respectively.
Number of increased seats are (140% of 5x), (150% of 7x) and (175% of 8x).
=> (140/100 x 5x ) , (150/100 x 7x) and (175/100 x 8x)
=> 7x , 21x/2 and 14x.
so  The required ratio = 7x : 21x/2 : 14x
=> 14x : 21x : 28x
=> 2 : 3 : 4.

5(B)Explanation:
Dog : Hare = (3*3) leaps of hare : 5 leaps of hare
= 9 : 5

6(D)Explanation:
Quantity of milk = (60 x 2/3) litres = 40 litres.
Quantity of water in it = (60- 40) litres = 20 litres.
New ratio = 1 : 2
Let quantity of water to be added further be x litres.
Then, milk : water =  (40/20 + x)  .
Now, (40/20+x) = 1/2
=> 20 + x = 80
x = 60.
so Quantity of water to be added = 60 litres.

7(A)Explanation:
In this type of question, we will first try to calculate the ratio of two persons. Once we get ratio then we can easily get our answer. So lets solve this.
4/15 A = 2/5 B
A = (2/5*14/4) B
A = 3/2B
A/B = 3/2
A : B = 3 : 2
B's Share = 2/5*1210 = 484

8(B)Explanation:
Let the three parts be A, B, C. Then,
A : B = 2 : 3 and B : C = 5 : 8 =  (5 x 3/5) : (8 x 3/5) =  3 : 24/5
A : B : C = 2 : 3 : 24/5 = 10 : 15 : 24
B = (98 x 5/49) = 30.

9(D)Explanation:
Given ratio =  1/2 : 2/3 : 3/4   =  6 : 8 : 9.
so  1st part  = Rs.(782 x 6/23)  = Rs. 204

10(C)Explanation:
Let the number of 25 p, 10 p and 5 p coins be x, 2x, 3x respectively.
Then, sum of their values = Rs.(25x/100 + (10 x 2x)/100 + (5 x 3x)/100)
= Rs. 60x/100
So 60x/100 = 30     <=>   x = (30 x 100)/60 = 50
Hence, the number of 5 p coins = (3 x 50) = 150.

B. 5%
C. 4%
D. 7%

10. A trader gives 12% additional discount on the discounted price, after giving an initial discount of 20% on the labeled price of an item. The final sale price of the item is Rs.704. Find out the labeled price?
A. 1000
B. 2000
C. 1200
D. 920

1(A)Explanation :
Let cost price of goods be Rs 100.
Gain = 20%
Therefore, Selling price = Rs 120
Discount = 25%
Marked Price = (100/100-25)x120
= Rs. 160
i .e.  60% more

2(D)Explanation :
If a trader professes to sell his goods at cost price, but uses false weights, then
Gain% = {Error/(True value - Error) x 100}%
In the given question, Error = 1000 - 850 = 150
Thus, Gain% = {150/(1000 - 150) x 100}%
= 17 11/17%

3(D)Explanation :
Let the cost price be Rs. x.
Selling Price at 10% loss = 90x/100
Selling Price at 15% gain = 115x/100
Thus, according to the problem,
115x/100 - 90x/100 = 40
x = Rs.160

4(D)Explanation :
Let the Cost Price (CP) of one article = 1
=> CP of x articles = x ------------------------------(Equation 1)
CP of 20 articles = 20
Given that cost price of 20 articles is the same as the selling price of x articles
=> Selling price (SP) of x articles = 20--------------(Equation 2)
Given that Profit = 25%
(SP-CP/CP)=25/100=1/4------------( Equation 3)
Substituting equations 1 and 2 in equation 3,
(20-x)/x=1/4
80-4x=x
5x=80
x=80/5=16

5(B)Explanation:
Let C.P.= Rs. 100. Then, Profit = Rs. 320, S.P. = Rs. 420.
New C.P. = 125% of Rs. 100 = Rs. 125
New S.P. = Rs. 420.
Profit = Rs. (420 - 125) = Rs. 295.
Required percentage = (295/420 x 100)% = 1475/21 % = 70% (approximately).

6(C)Explanation :
Let CP = x
Percentage profit earned by selling an item for Rs. 1920
= (SP-CP/CP0 ×100
=(1920-x)/x×100
Percentage loss incurred by selling the same item for Rs. 1280
= (CP-SP)/CP×100
= (x-1280)/x ×100
Given that Percentage profit earned by selling an item for Rs. 1920=Percentage loss incurred by selling the same item for Rs. 1280
(1920-x)/x ×100 = x-1280/x ×100
(1920-x)/x = (x-1280)/x
1920–x = x–1280
2x=1920+1280=3200
x=3200/2
=1600
Required Selling Price = CP×125/100
=1600×125/100 =1600×5/4
=400×5=2000

7(D)Explanation:
Suppose, number of articles bought = L.C.M. of 6 and 5 = 30.
C.P. of 30 articles = Rs.(5/6 x 30) = Rs. 25.
S.P. of 30 articles = Rs.(6/5 x 30) = Rs. 36.
Gain % =  (11/25 x 100) % = 44%.

8(A)Explanation:
C.P. of 1 orange = Rs.(350/100) = Rs. 3.50
S.P. of 1 orange = Rs (48/12) = Rs. 4
Gain% = (0.50/3.50  x 100) %  = 100/7 % = 14 2/7%

9(B)Explanation :
CP of 1st variety rice=20
CP of 2nd variety rice=36
CP of the 56 kg rice mixture=(26×20+30×36)=520+1080=1600
SP of the 1 kg rice mixture=30
SP of the 56 kg rice mixture=30×56=1680
Gain=SP-CP=1680-1600=80
Gain%=Gain/CP×100=80/1600×100=100/20=5%

10(A)Explanation :
Let the labeled price=x
SP=704
Initial Discount=20%
Price after initial discount=x×80/100
Price after additional discount=x×80/100 × 88/100
=> x×80/100 × 88100=704
=>x×4/5 × 22/25=704
=>x=704×25/22 × 5/4=176×25/22×5
=8×25×5=40×25=1000

A. 1/3
B. 2/3
C. 2/5
D. 3/5

1( B)Explanation :
Assume that a container contains x of liquid from which y units are taken out and replaced by water. After n operations, the quantity of pure liquid
=x(1-y/x)^n
Hence milk now contained by the container = 40(1-4/40)^3
=40(1-1/10)^3
=40×9/10×9/10×9/10 =(4×9×9×9)/100 =29.16

2(C)Explanation:
Suppose the vessel initially contains 8 litres of liquid.
Let x litres of this liquid be replaced with water.
Quantity of water in new mixture = (3 - 3x/8 + x) litre
Quantity of syrup in new mixture = (5 - 5x/8) litres
So  (3 - 3x/8 + x)  = (5 - 5x/8) litres
=> 5x + 24 = 40 - 5x
=>10x = 16
=> x = 8/5 .
So, part of the mixture replaced = (8/5 x 1/8) = 1/5

3(C)Explanation :
Tea worth Rs. 126 per kg and Rs. 135 per kg are mixed in the ratio 1 : 1
So their average price = (126+135)/2=130.5
Hence let's consider that the mixture is formed by mixing two varieties of tea.
one at Rs. 130.50 per kg and the other at Rs. x per kg in the ratio 2 : 2, i.e., 1 : 1. Now let's find out x.
By the rule of alligation, we can write as

Cost of 1 kg of 1st kind of tea               Cost of 1 kg of 2nd kind of tea
(130.50)                                                      (x)

Mean Price
(153)

(x - 153)                                                                      (22.50)

=>(x - 153) : 22.5 = 1 : 1
=>x - 153 = 22.50
=> x = 153 + 22.5 = 175.5

4(C)Explanation:
Suppose the can initially contains 7x and 5x of mixtures A and B respectively.
Quantity of A in mixture left = (7x - 7/12 x 9)litres
= (7x - 21/4) litres.
Quantity of B in mixture left = (5x - 5/12  x 9) litres
= (5x - 15/4)  litres.
So (7x - 21/4)/((5x - 15/4) +9) = 7/9
=> (28x - 21)/(20x + 21) = 7/9
=> 252x - 189 = 140x + 147
=> 112x = 336
=> x = 3.
So, the can contained 21 litres of A.
.
5(D)Explanation :
Let Cost Price(CP) of 1 litre spirit be Rs.1
Quantity of spirit in 1 litre mixture from vessel A = 5/7
Cost Price(CP) of 1 litre mixture from vessel A = Rs. 5/7
Quantity of spirit in 1 litre mixture from vessel B = 7/13
Cost Price(CP) of 1 litre mixture from vessel B = Rs. 7/13
Quantity of spirit to be obtained in 1 litre mixture from vessel C = 8/13
Cost Price(CP) of 1 litre mixture from vessel C = Rs. 8/13 = Mean Price
By the rule of alligation, we can write as

CP of 1 litre mixture     CP of 1 litre mixture
from vessel A (5/7)      from vessel B (7/13)

Mean Price
(8/13)

8/13 - 7/13 = 1/13                 5/7 - 8/13 = 9/91

=> Mixture from Vessel A : Mixture from Vessel B = 1/13 : 9/91 = 7 : 9 = Required Ratio

6(C)Explanation:
By the rule of alligation:
Cost of 1 kg pulses of       Cost of 1 kg pulses of
1st kind Rs.  (15)               2nd kindRs. (20)

Mean Price
Rs. (16.50)

(3.50)                                    (1.50)

Required rate = 3.50 : 1.50 = 7 : 3.

7(C)Explanation :
Let initial quantity of wine = x litre
After a total of 4 operations, quantity of wine = x(1-y/x)^n=x(1-8/x)^4
Given that after a total of 4 operations, the ratio of the quantity of wine left in cask to that of water = 16 : 65
Hence we can write as (x(1-8/x)^4)/x =16/81
(1-8/x)^4 = (2/3)^4
(1-8/x) = 2/3
(x-8/x) = 2/3
3x-24=2x
x=24

8(C)Explanation:
Let C.P. of 1 litre milk be Re. 1
Then, S.P. of 1 litre of mixture = Re. 1, Gain = 25%.
C.P. of 1 litre mixture = Re.(100/125 x 1) = 4/5
By the rule of alligation, we have:

C.P. of 1 litre of milk       C.P. of 1 litre of water
Re. (1)                                     (0)

Mean Price
Re. 4/5

4/5                                       1/5

Ratio of milk to water = 4/5 : 1/5 = 4 : 1.
Hence, percentage of water in the mixture = (1/5 x 100)% = 20%

9(D)Explanation :
Concentration of alcohol in 1st Jar = 40%
Concentration of alcohol in 2nd Jar = 19%
After the mixing, Concentration of alcohol in the mixture = 26%
By the rule of alligation,
Concentration of alcohol in  Concentration of alcohol in
1st Jar(40%)                                 2nd Jar (19%)

Mean
(26%)

(7)                                             (14)

Hence ratio of 1st and 2nd quantities = 7 : 14 = 1 : 2

10(B)Explanation:
By the rule of alligation, we have:

Strength of first jar                Strength of 2nd jar
(40%)                                     (19%)

Mean
Strength
(26%)

(7)                                             (14)

So, ratio of 1st and 2nd quantities = 7 : 14 = 1 : 2
Required quantity replaced = 2/3
