Question No 2

Present ages of Sameer and Anand are in the ratio of 5/4 respectively. Three years hence, the ratio of their ages will become 11/9 respectively. What is Anand's present age in years?

Select the correct answer


Solution!
Let the present ages of Sameer and Anand be 5x years and 4x years respectively.

Then,
(5x+3)/(4x+3) = 11/9
9(5x + 3) = 11(4x + 3)
45x + 27 = 44x + 33
45x - 44x = 33 - 27
x = 6

nand's present age = 4x = 24 years.

Question No 3

Select the correct answer


Solution!
(C.P. of 17 balls) - (S.P. of 17 balls) = (C.P. of 5 balls)

C.P. of 12 balls = S.P. of 17 balls = $720

C.P. of 1 ball = $60.

Question No 8

With an increase of 12% salary of Ali became Rs13440. What was his salary before increase?

Select the correct answer


Solution!
Let before increase Ali's salary was x.
12% of x = 12x/100 = 3x/25

Now
13440 - 3x/25 = x
336000 - 3x = 25x
336000 = 28x
x = 12000

Hence Ali's salary before increase was Rs. 12000.

Question No 9

Meena is thrice as old as Sheraz. Fatima will be twice as old as Meena 6 years hence. Six years ago Sheraz was five years old. What is Fatima's present age?

Select the correct answer


Solution!
Let present age of Sheraz is x and present age of Fatima is y.

So,
Meena's age = 3x

Given that
y+6 = 2(3x+6) ...(1)
and
x-6 = 5
x = 11

Put value of x in equation(1)

y+6 = 2(33+6)
y+6 = 78
y = 72

Hence Fatima's present age is 72 years..

Question No 14

A can finish a work in 24 days, B in 9 days and C in 12 days. B and C start the work but are forced to leave after 3 days. The remaining work was done by A in

Select the correct answer


Solution!
(B + C)'s 1 day's work = (1/9 + 1/12) = 7/36

Work done by B and C in 3 days = (7/36 * 3)
= 7/12

Remaining work = (1 - 7/12)
= 5/12

Now, 1/24 work is done by A in 1 day.

So, 5/12 work is done by A in (24 * 5/12) = 10 days..

Question No 15

Question No 16

What is the angle between the hands of a clock at 3:35 pm?

Select the correct answer


Solution!
At 3:35 hour hand is nearly at 3
Minute hand is at 7

Angle between 3 and 7 is 120 degree.

Hour hand move 1/2 degree in one minute.

In 35 Minutes hour hand will move 1/2 * 35 = 17.5 degree

Hence, Angle between hands is 120 - 17.5 = 102.5 degree.

Question No 17

The reflex angle between the hands of a clock at 10:25 is

Select the correct answer


Solution!
Angle traced by hour hand in 125/12 hrs = (360/12 * 125/12) = 625/2 degree

Angle traced by minute hand in 25 min = (360/60 * 25) = 150 degree

So, Reflex angle = 360 - (625/2 - 150) = 197.5 degree.

Question No 18

A boat takes 90 minutes less to travel 36 miles downstream than to travel the same distance upstream. If the speed of the boat in still water is 10 mph, the speed of the stream is

Select the correct answer


Solution!
Let the speed of the stream x mph.

Then,
Speed downstream = (10 + x) mph

Speed upstream = (10 - x) mph

So, [36/(10 - x)] - [36/(10 + x)] = 90/60
(72x)*60 = 90 (100 - x*x)
(x+ 50)(x - 2) = 0

Hence, x = 2 mph..

Question No 19

Ten years ago a father was seven times as old as his son, two years hence, twice his age will be equal to five times his son's. What is the present age of son?

Select the correct answer


Solution!
Let present age of son is x and present age of father is y.

Given that
y-10 = 7(x-10)
y-10 = 7x-70
y-7x = -70+10
7x-y = 60 ...(1)

and also given that
2(y+2) = 5(x+2)
2y+4 = 5x+10
2y-5x = 6 ...(2)By simultaneously soving equation(1) and equation(2)
x = 14

Hence present age of son is 14 years..

A can do a piece of work in 4 hours; B and C together can do it in 3 hours,while A and C together can do it in 2 hours.How long will B alone take to do it?

Select the correct answer


Solution!
A's 1 hour's work = 1/4

(B + C)'s 1 hour's work = 1/3

(A + C)'s 1 hour's work = 1/2

(A + B + C)'s 1 hour's work = (1/4 + 1/3) = 7/12

B's 1 hour's work = (7/12 - 1/2) = 1/12

Hence, B alone will take 12 hours to do the work..

Select the correct answer


Solution!
Man's rate in still water = (15 - 2.5) km/hr
= 12.5 km/hr

Man's rate against the current = (12.5 - 2.5) km/hr
= 10 km/hr.

Question No 30

A train speeds past a pole in 15 seconds and a platform 100 m long in 25 seconds. Its length is

Select the correct answer


Solution!
Let the length of the train be x metres and its speed by y m/sec.

Then, x/y = 15
y = x/15

So, (x+100)/25 = x/15
15(x + 100) = 25x
15x + 1500 = 25x
1500 = 10x
x = 150 m.

Question No 31

25 tailors can make 35 dresses in 1 day. How many dresses can 6 tailors make in 5 days?

Select the correct answer


Solution!
Let x dresses can be made.
As dresses are directly proportional to tailors and days so
x/35 = (6/25)*(5/1)
x = 42

Hence 42 dresses can be made by 6 tailors in 5 days..

Question No 32

Anil's swimming speed in still water is 14 km/h and speed of water is 4 km/h. How long will it take him to go upstream 50 km?

Select the correct answer


Solution!
Anil's swimming speed in still water = u = 14 Km/h
Speed of water = v = 4 Km/h
Total upstream speed = u-v = 14-10 = 10 Km/h
Distance to cover = S = 50Km

time = distance/speed
By putting values
time = t = 50/10 = 5 hours.

Question No 36

A and B can do a work in 8 days, B and C can do the same work in 12 days. A, B and C together can finish it in 6 days. A and C together will do it in

Select the correct answer


Solution!
(A + B + C)'s 1 day's work = 1/6

(A + B)'s 1 day's work = 1/8

(B + C)'s 1 day's work = 1/12

So, (A + C)'s 1 day's work = (2* 1/6) - (1/8 + 1/12)
= (1/3 - 5/24) = (3/24) = 1/8

So, A and C together will do the work in 8 days..

Solution!
P % Q = P is the mother of Q

Q + R = Q is the father of R

R - T = R is the brother of T

Hence, Q is the father of T

T x K = T is the daughter of K

Hence, Q is the husband of K.

Therefore, P is the mother-in-law of K..

Select the correct answer


Solution!
Let present age of the greater fellow is x and present age of smaller fellow is y.

Given that xy = 24 ...(1)
and

x = (3/2)y
Put value of x in equation(1).

(3/2)y^2 = 24
y^2 = 24*(2/3)
y^2 = 16
y = 4

Hence age of smaller fellow is 4 years..

Question No 44

The ages of C and D are in 6/11 and E is 6 years younger than D. If the sum of ages is 134, then what is the age of D?

Select the correct answer


Solution!
Given that
C/D = 6/11
C = (6/11)D ...(1)

and
C+D+E = 134

As E is 6 years younger from D so we can put D-6 instead of D
C+D+D-6 = 134
C+2D = 140
Put value of C from equation(1)
(6/11)D+2D = 140
6D+22D = 140
28D = 1540
D = 55

Hence D is 55 years old..

Solution!
Speed of train relative to man = (60 + 6) km/hr = 66 km/hr.
= 66 * (5/18) = (55/3)m/s

Hence, Time taken to pass the man
= 110 * (3/55) = 6 seconds.

Question No 53

A train overtakes two persons who are walking in the same direction in which the train is going, at the rate of 2 kmph and 4 kmph and passes them completely in 9 and 10 seconds respectively. The length of the train is

Select the correct answer


Solution!
2 kmph = 2 * (5/18)m/s
= 5/9 m/s

4 kmph = 4 * (5/18)m/s
= 10/9 m/s

Let the length of the train be x metres and its speed by y m/sec.

then, x/[y - (5/9)] = 9
and x/[y - (10/9)] = 10

So, 9y - 5 = x
and 10(9y - 10) = 9x

9y - x = 5
and 90y - 9x = 100

On solving, we get
x = 50

Hence, Length of the train is 50 m..

Solution!
Let C's present age is x and his mother's age is y.

Given that
y = 4(x-10)
y = 4x-40
4x-y = 40 ...(1)

and
y+10 = 2x
2x-y = 10 ...(2).

By simultaneously solving equation(1) and equation(2) we find
x = 15

Hence C is 15 years old..
