Answers :
1) Answer: A
Milk in 60 liters = 3/5 * 60 = 36 liters
Water in 60 liters = 2/5 * 60 = 24 liters
Milk in 20 liters = 3/5 * 20 = 12 liters
Water in 20 liters = 2/5 * 20 = 8 liters
Required ratio = (36 – 12):(24 – 8)
= 24:16
= 3:2
2) Answer: D
Milk in 20 liters = 3/5 * 20 = 12 liters
Water in 20 liters = 2/5 * 20 = 8 liters
(3x – 12)/(2x – 8 + 4) = 6/5
15x – 60 = 12x – 24
x = 12
Quantity of mixture = 12 * 5 = 60 liters
3) Answer: C
Milk in 60 liters = 60 * 7/12 = 35
Water in 60 liters = 60 * 5/12 = 25
(35 – 7x/12)/(25 – 5x/12 + 13) =3/4
114 – 5x/4 = 140 – 7x/3
7x/3 – 5x/4 = 26
x = 24
Final quantity of water = 25 – (5 * 24/12) + 13 = 28 liters
4) Answer: A
Initial quantity of mixture = 100x
Oil = 100x * 60/100 = 60x
Water = 40/100 * 100x = 40x
(60x – 6)/40x = 1/1
60x – 6 = 40x
20x = 6
100x = 6 * 5 = 30
5) Answer: C
Milk vessel A = 60 * 3/5 = 36
Water in vessel A = 60 * 2/5 = 24
(36 + 5x/9)/(24 + 4x/9) = 7/5
168 + 28x/9 = 180 + 25x/9
3x/9 = 12
x = 36
6) Answer: A
Oil = 3/5 * 120 = 72 liters
Water = 2/5 * 120 = 48 liters
25% of mixture = 25/100 * 120 = 30
Oil in 30 liters = 30 * 3/5 = 18
Water in 30 liters = 30 * 2/5 = 12
Required ratio = (72 – 18): (48 – 12 + 30)
= 54:66
= 9:11
7) Answer: B
The initial quantity of milk = 55x
The initial quantity of water = 45x
Milk in 120 liters = 55/100 * 120 = 66 liters
Water in 120 liters = 45/100 * 120 = 54 liters
(55x – 66)/(45x – 54 + 4) = 110/100
495x – 550 = 550x – 660
x = 2
Final quantity of water = 45 * 2 – 50 = 40 liters
8) Answer: B
Milk in Vessel A = 75 * 68/100 = 51
Water in Vessel A = 75 * 32/100 = 24
Ratio of milk and water in B = 275:100 = 11:4
Milk in Vessel B = 90 * 11/15 = 66
Water in Vessel B = 90 * 4/15 = 24
(51 + 66)/(24 + 24 + x) = 2/1
96 + 2x = 117
x = 10.5
9) Answer: B
Milk = 2/3 * 180 = 120Liters
Water = 180 – 120 = 60Liters
120 = (180 + x) * 60%
12000=10800+60x
1200=60x
=> x = 20Liters
10) Answer: C
Initial quantity = 8x
Oil = 5x
Water = 3x
Oil in 120 liters = 120 * 5/8 = 75 liters
Water in 120 liters = 120 * 3/8 = 45 liters
(5x – 75 + 25)/(3x – 45 + 5) = 2/1
6x – 80 = 5x – 50
x = 30
Initial quantity = 8 * 30 = 240 liters

E.20
Answers :
11) Answer: B
Milk in vessel A = 3/5 * 60 = 36 liters
Water in vessel A = 2/5 * 60 = 24 liters
(36 + 6x/11)/(24 + 5x/11) = 15/11
(396 + 6x) * 11 = 15 * (264 + 5x)
396 = 9x
x = 44 liters
12) Answer: E
Milk = 5/9 * 45 = 25 liters
Water = 4/9 * 45 = 20 liters
25/(20 + x) = 4/5
80 + 4x = 25 * 5
4x = 45
x = 11.25 liters
13) Answer: E
Milk = 3/5 * 30 = 18 liters
Water = 2/5 * 30 = 12 liters
(18 + 22)/(12 + x) = 4/5
40/(12 + x) = 4/5
x = 38 liters
14) Answer: A
Milk in vessel B = 7/12 * 60 = 35 liters
Water in vessel B = 5/12 * 60 = 25 liters
Let us take the quantity of mixture in vessel A be x
(4x/7 + 35)/(3x/7 + 25) = 11/8
33x/7 + 275 = 32x/7 + 280
x/7 = 5
x = 35 litres
15) Answer: Â C
CP of the mixture = 50/125 * 100 = 40
= (50 – 40): (40 – 36) = 10: 4 = 5: 2
5: 2 = x: 20
x = 50 kg
16) Answer: C
Milk in 40 liters = 3/5 * 40 = 24 liters
Water in 40 liters = 2/5 * 40 = 16 liters
(24 – (3x/5))/(16 – (2x/5) + 20) = 3/7
(120 – 3x)/(180 – 2x) = 3/7
540 – 6x = 840 – 21x
15x = 300
x = 20 liters
17) Answer: D
Milk in 45 liters = 3/5 * 45 = 27 liters
Water in 45 liters = 2/5 * 45 = 18 liters
(27 – 3x/5)/(18 – 2x/5 + x) = ½
90 – 2x + 5x = 270 – 6x
9x = 180
x = 20 liters
18) Answer: A
Required ratio = (3/5 + 5/9 + 2/3):(2/5 + 4/9 + 1/3)
= (27 + 25 + 30):(18 + 20 + 15)
= 82:53
19) Answer: C
4x/(x + 25) = 16/9
16x + 25 * 16 = 36x
20x = 400
x = 20
Total quantity = 20 * 5 = 100 liters
20) Answer: B
60 * (1 – (x/60))3 = 60 – 29.28
60 * (1 – (x/60))3 = 30.72
(1 – x/60)3 = 512/1000
1 – x/60 = 8/10
x = 12 liters

Answers :
21) Answer: C
Milk in Jar A = 3/5
Water in Jar A = 2/5
Milk in Jar B = 4/7
Water in Jar B = 3/7
Milk and water in Jar C = (3/5 + 4/7):(2/5 + 3/7)
=(21 + 20):(14 + 15)
= 41:29
22) Answer: B
Milk in 20 litres = 3/5 * 20 = 12 litres
Water in 20 litres = 2/5 * 20 = 8 litres
(3x – 12)/(2x – 8 + 24) = 1/2
2x + 16 = 6x – 24
4x = 40
x = 10 litres
Total mixture = 5 * 10 = 50 litres
23) Answer: B
Milk in vessel A = 70 * 4/5 = 56 liters
Milk in vessel B = 90 * 5/9 = 50 liters
Required percentage = [(56 + 50)/(70 + 90)] *100
= 66.25%
24) Answer: D
Total mixture = 80 litres
The milk and water in the ratio = 3: 2
Milk = (80/5) * 3 = 48 litres, Water = (80/5) * 2 = 32 litres
Given,
48/(32 + x) = 1/1
48 = 32 + x
x = 48 – 32 = 16 litres
25) Answer: C
Milk in 16 liters = 5/8 * 16 = 10 liters
Water in 16 liters = 3/8 * 16 = 6 liters
(5x – 10) / (3x – 6 + 16) = 15/17
45x + 150 = 85x – 170
40x = 320
x = 8 liters
Total quantity of the mixture = 8 * 8 = 64 liters
26) Answer: B
Milk = 60 * 4/5 = 48 liters
Water = 60 * 1/5 = 12 liters
Milk in 20 liters = 20 * 4/5 = 16 liters
Water in 20 liters = 20 * 1/5 = 4 liters
(48 – 16 + x)/(12 – 4) = 5/1
40 = 32 + x
x = 8 liters
27) Answer: D
Milk = 5/8 * 64 = 40 liters
Water – 3/8 * 64 = 24 liters
(40 – 5x/8) / (24 – 3x/8 + x) = 25/39
(320 – 5x) * 39 = 25 * (192 + 5x)
12480 – 195x = 4800 + 125x
320x = 7680
x = 24 liters
28) Answer: C
CP of mixture = (67.5 *100)/125 = Rs. 54
= > 2 : 1
Total kg of variety 1 rice = 25 * 2 = 50 kg
29) Answer: B
Milk in 80 litres = 11/20 * 80 = 44 litres
Water in 80 litres = 9/20 * 80 = 36 litres
Milk in 40 litres = 11/20 * 40 = 22 litres
Water in 40 litres = 9/20 * 40 = 18 litres
(44 – 22 + 8)/(36 – 18 + x) = 1/1
30 = 18 + x
x = 12 litres
30) Answer: D
Milk in 36 liters = 36 * 5/9 = 20 liters
Water in 36 liters = 36 * 4/9 = 16 liters
(5x – 20)/(4x – 16 + 10) = 5/6
20x – 30 = 30x – 120
10x = 90
x = 9 liters
Total quantity = 9 * 9 = 81 liters

32) Answer: D
Milk=40 liters
Water=20 liters
Milk and water=40:20=2:1
Milk in 18 liters of mixture=2/3 * 18=12 liters
Water in the 18 liter mixture=1/3 * 18=6 liters
Milk in the final mixture=40 – 12=28
Water in the final mixture=20 – 6 + 18=32
Required ratio=28:32
=7:8
33) Answer: C
Milk = 7/10 * 90 = 63
Water = 3/10 * 90 = 27
Milk in 20 liters of the mixture = 20 * 7/10 = 14
Water in 20 liters of the mixture = 20 * 3/10 = 6
Required ratio = (63 – 14)/(27 – 6 + 20)
= 49/41
34) Answer: AÂ Â Â Â Â
CP of the mixture = 51/150 * 100 = 34
The required ratio = 3: 2
35) Answer: C
5x/(3x + 20) = 15/19
45x + 300 = 95x
50x = 300
x = 6 liters
Initial quantity of the water = 3 * 6 = 18 liters
36) Answer: C
Milk = 2/3 * 60 = 40
Water = 1/3 * 60 = 20
Milk in 24 liter = 2/3 * 24 = 16
Water in 24 liter = 1/3 * 24 = 8 liters
Final quantity of the milk = 40 – 16 = 24
Final quantity of the water = 20 – 8 + 24 = 36
Required percentage = 24/36 * 100 = 66.67%
37) Answer: B
Petrol = 40/100 * 80 = 32
Kerosene = 60/100 * 80 = 48
(32 + x)/48 = 60/40
2 * (32 + x) = 48 * 3
64 + 2x = 144
x = 40 liters
38) Answer: B
Milk in Jar A = 60 * 2/3 = 40 liters
Water in Jar A = 60 * 1/3 = 20 liters
Milk in x liter = x * 2/3
Water in x liter = x * 1/3
(40 – 2x/3 + 10) / 20 – x/3 = 11/4
(120 – 2x + 30) / (60 – x) = 11/4
660 – 11x = 600 – 8x
3x = 60
x = 20 liters
39) Answer: B
Milk = 5/9 * 90 = 50 litres
Water = 4/9 * 36 = 40 litres
Milk in 45 litres = 5/9 * 45 = 25 litres
Water in 18 litres = 4/9 * 45 = 20 litres
(50 – 25)/(40 – 20 + x) = 2/3
40 + 2x = 75
2x = 35
x = 17.5 litres
40) Answer: B
Milk in 20 litres = 3/5 * 20 = 12 litres
Water in 20 litres = 2/5 * 20 = 8 litres
(3x – 12)/(2x – 8 + 24) = 1/2
2x + 16 = 6x – 24
4x = 40
x = 10 litres
