Ten years ago Akram was thrice as old as Aslam was, but 10 years hence, he will be only twice as old. What is Akram's present age?

#### Select the correct answer

Solution!
Let Aslam's present age is x and Akram's present age is y.

Given that
y-10 = 3(x-10)
y-10 = 3x-30
y-3x = -20
3x-y = 20 ...(1)

and also given that
y+10 = 2(x+10)
y+10 = 2x+20
y-2x = 10 ...(2)

By simultaneously solving equation(1) and equation(2)
y=70

Hence Akram's present age is 70 years..

#### Question No 15

A man can row 1 km upstream in 20 minutes, and downstream in 15 minutes. What is the speed of the current?

#### Select the correct answer

Solution!
20 minutes = 20/60 = 1/3 hours
Upstream distance covered in 1/3 hours = 1 Km
Upstream distance covered in 1 hour = 1/(1/3) = 3 Km
Upstream speed = y = 3 Km/h

Now
15 minutes = 15/60 = 1/4 hours
Downstream distance covered in 1/4 hours = 1 Km
Downstream distance covered in 1 hour = 1/(1/4) = 4 Km
Downstream speed = 4 Km/h

speed of water = (1/2)*(4-3) = 1/2 = 0.5 Km/h.

= 4 hours.

#### Question No 20

A clock is started at noon.By 10 minutes past 5, the hour hand has turned through ...

#### Select the correct answer

Solution!
Angle traced by hour hand in 12 hrs = 360 degree

Angle traced by hour hand in 5 hrs 10 min. i.e.,
31/6 hrs = (360/12 * 31/6) = 155 degree.

#### Question No 21

A does 80% of a work in 20 days. He then calls in B and they together finish the remaining work in 3 days. How long B alone would take to do the whole work?

#### Select the correct answer

Solution!
Whole work is done by A in (20 * 5/4) = 25 days

Now, (1 - 4/5) i.e., 1/5 work is done by A and B in 3 days.

Whole work will be done by A and B in (3 x 5) = 15 days.

A's 1 day's work = 1/25
(A + B)'s 1 day's work = 1/15

So, B's 1 day's work = (1/15 - 1/25) = 4/150 = 2/75

Hence, B alone would do the work in 75/2 = 37.5 days..

#### Question No 22

Father is aged three times more than his son Ronit. After 8 years, he would be two and a half times of Ronit's age. After further 8 years, how many times would he be of Ronit's age?

#### Select the correct answer

Solution!
Let Ronit's present age be x years. Then, father's present age =(x + 3x) years
= 4x years.

(4x + 8) = 5/2 (x+8)
8x + 16 = 5x + 40
3x = 24
x = 8

Hence, required ratio = (4x+16)/(x+160)
= 48/24 = 2.

#### Question No 26

X can do a piece of work in 40 days.He works at it for 8 days and then Y finished it in 16 days.How long will they together take to complete the work?

#### Select the correct answer

Solution!
Work done by X in 8 days = (1/40 * 8)
= 1/5

Remaining work = (1 - 1/5)
4/5

Now, 4/5 work is done by Y in 16 days.

Whole work will be done by Y in (16 * 5/4)
= 20 days

So,
X's 1 day's work = 1/40
Y's 1 day's work = 1/20

(X + Y)'s 1 day's work = (1/40 + 1/20) = 3/40

Hence, X and Y will together complete the work in 40/3 days.

#### Question No 27

A 270 metres long train running at the speed of 120 kmph crosses another train running in opposite direction at the speed of 80 kmph in 9 seconds. What is the length of the other train?

#### Select the correct answer

Solution!
Relative speed = (120 + 80) km/hr
= 200(5/18)m/s
= (500/9)m/s

Let the length of the other train be x metres

Then,
(x+270)/9 = 500/9
x + 270 = 500

Hence, x = 230.

#### Question No 28

If one third of the staff at school are teachers find the ratio between teachers to non-teachers.

#### Select the correct answer

Solution!

#### Question No 29

A father said to his son, "I was as old as you are at the present at the time of your birth". If the father's age is 38 years now, what was the son's age five years back?

#### Select the correct answer

Solution!
Let the son's present age be x years.

Then
(38 - x) = x

2x = 38
x = 38/2 = 19

Son's age 5 years back = 19-5 = 14 years.

#### Question No 30

#### Question No 31

A train 125 m long passes a man, running at 5 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is

#### Select the correct answer

Solution!
Speed of the train relative to man = (125/10) m/s
= (25/2)m/s
= (25/2) * (18/5)km/hr
= 45 km/hr

Let the speed of the train be x km/hr.
Then,
relative speed = (x - 5) km/hr

x - 5 = 45
Hence, x = 50 km/hr.

#### Question No 32

A train travelling at the speed of 10m/s can cross a bridge in 23 seconds. If length of the train is 120 meters. What is length of the bridge?

#### Select the correct answer

Solution!
Speed = v = 10m/s
Time = t = 23s
Length of train = L1 = 120m
Length of bridge = L2 = ?

t = (L1+L2)/v
By putting values
23 = (120+L2)/10
L2 = 230 - 120 = 110m

Hence bridge is 110m long..
