X-y=28
From Option (A)
x+y=583/11
x+y=53
2x=81
X=40.5
Y=12.5
Ratio=40.5:12.5=81:25
This not satisfies the given condition.
From Option (B)
x-y =28kmph
x+y=924/11=84
2x=112
X=56
Y=56-28=28
Ratio=56:28=2:1
This satisfies the given condition.
From Option (C)

This not satisfies the given condition.
3) Answer: b)
Speed of the boat=7x
Speed of the stream=x
Upstream speed = (7x-x) =6x
Downstream speed = (7x+x) =8x
Upstream speed, 6x=21*60/70
6x=18kmph
X=3kmph
Downstream speed=8(3) =24kmph

This not satisfies the given condition.
From Option (D)
Time=60/24=2.5 hr
This not satisfies the given condition.
4) Answer: c)
Length of the train=x
Option (A)
Length of the platform = 400 m
Train crosses a pole and platform in 24 and 12
seconds respectively,
(x+400)/24 = x/12
X+400 = 2x
X=400 m
Speed of the train = 400/12 = 100/3 m/s
Train crosses a man and man’s speed x km/hr
400/(100/3 +z) = 9
400 = 900/3 +9z
300/3 = 9z
Z= 100/9 = 100/9 * 18/5 = 40 km/hr
This option is not satisfies the given
condition.
From Option (B)
Length of the platform = 300 m
Train crosses a pole and platform in 24 and 12
seconds respectively,
(x+300)/24 = x/12
X+300 = 2x
X=300 m
Speed of the train = 300/12 = 25 m/s
Train crosses a man and man’s speed x km/hr
300/(25 +z) = 9
300 = 225 +9z
75 = 9z
Z= 75/9 = 75/9 * 18/5 = 30 km/hr
This option is not satisfies the given
condition.
From option(C)
Length of the platform = 200 m
Train crosses a pole and platform in 24 and 12
seconds respectively,
(x+200)/24 = x/12
X+200 = 2x
X=200 m
Speed of the train = 200/12 = 50/3 m/s
Train crosses a man and man’s speed x km/hr
200/(50/3 +z) = 9
200 = 450/3 +9z
150/3 = 9z
Z= 50/9 = 50/9 * 18/5 = 20 km/hr
This option satisfies the given condition.
From Option (D)
Length of the platform = 180 m
Train crosses a pole and platform in 24 and 12
seconds respectively,
(x+180)/24 = x/12
X+180 = 2x
X=180 m
Speed of the train = 180/12 = 15 m/s
Train crosses a man and man’s speed x km/hr
180/(15 +z) = 9
180 = 135 +9z
45 = 9z
Z= 45/9 = 45/9 * 18/5 = 18 km/hr
This option is not satisfies the given
condition.
5) Answer: a)
From Option (A)
Profit ratio= (2550*4 + 5100*6) : (2700*12)
=34:27
A’s share= (34/61)*12200= 6800
This is satisfies the given condition.
From Option (B)
Profit ratio = (2550*4 + 5100*6) : (3000*12)
=17:15
A’s Share= (17/32)*12200=6481.25
This is not satisfies the given condition.
From Option (C)
Profit ratio= (2550*4 + 5100*6): (3200*12) =
17:16
A’s share = (17/33)*12200=6284.84
This is not satisfies the given condition.
From Option (D)
Profit ratio= (2550*4 +
5100*6):(2500*12)=34:25
A’s share=34/59*12200=7030.5
This is not satisfies the given condition.
6 - 10
Total population = 600000
Total Male and Female = (5:3) ,
male= 375000
Female= 225000
Literate male to illiterate male 4:1
So Literate male= 300000
Illiterate male = 75000.
Population of village A to B is 17:13
A=340000.
B=260000.
Males in villages
Males in village A to b is 7:8
So males in Village A= 175000
Males in village B = 200000
Females in village:
Females in village A : 165000
Females in village B =6000
Adult is 80%=480000
Child is 2%=12000
Senior c =108000.
Answer: C
Literate people = 300000 +78750 =378750
Senior Citizens = 108000
Difference = 270750
7.Answer: C
Total literate males = 3, 00, 000.
From village A, (45%) = 3, 00,000 *(45/100) =135000
Illiterate females = 1, 46,250
= (135000/146250) *100 =92.3 =92%
8.Answer: D
Males in Village B = 2, 00, 000
Adult females in survey = 1, 80,000
Ratio = 200000:180000 = 10:9
9.Answer: A
Total number of children = 12,000
Difference of populations
Of Village A to
B = 340000
-260000 =80000
= (80,000 -12,000) /80,000 *100
= (68/80) *100 = 85%
10.Answer: B
Sum of Illiterates= 75000+146250 = 2, 21,250
Total population = 6, 00,000
Difference = 6, 00,000 -2, 21,250 = 378750
