#### Question No 1

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?

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..

#### Question No 3

John's income increased from $12000 to$14400. What is percentage increase in his income?

Solution!
Increase in income = 14400 - 12000 = 2400

Percentage increase = (2400/12000)*100 = 20%.

#### Question No 4

Which of the following is an integer that has a remainder of 1 when it is divided by 4,5 and 6?

Solution!
Least common multiple of 4,5 and 6 is 60 so 61 is an integer that has a remainder of 1 when it is divided by 4,5 and 6..

#### Question No 8

A father is 3 years older than 3 times the age of his son. If the sum of their ages is 31 years, how old was father 3 years ago?

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

Given that
y = 3x+3 ...(1)

and
x+y = 31
x = 31-y

Put value of x in equation(1)
y = 3(31-y)+3
y = 93-3y+3
4y = 96
y = 24

Three years ago
y = 24-3
y = 21

Hence father was 21 years old 3 years ago..

#### Question No 9

Ali and Nadeem are brothers. Maria and Mariam are sisters. If Ali's son is Mariam's brother, them what is the relation of Nadeem to Maria?

Solution!
"Ali's son is Mariam's brothers" means Mariam and Maria are Ali's daughters.

So Nadeem (brother of Ali) is Uncle of Maria..

#### Question No 10

An accurate clock shows 8 o'clock in the morning. Through how many degrees will the hour hand rotate when the clock shows 2 o'clock in the afternoon?

Solution!
Angle traced by the hour hand in 6 hours = (360/12)*6 = 180 degree.

#### Question No 11

Solution!
I am the husband of Preety's daughter because she is mother of my son. So Preety is my mother-in-law..

#### Question No 13

A boatman goes 2 km against the current of the stream in 1 hour and goes 1 km along the current in 10 minutes. How long will it take to go 5 km in stationary water?

Solution!
Rate downstream = (1/10) * 60 km/hr = 6 km/hr

Rate upstream = 2 km/hr

Speed in still water = (1/2)(6 + 2) km/hr = 4 km/hr

Hence, Required time = 5/4 hrs = 1 hr 15 min..

#### Question No 14

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?

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..

#### Question No 15

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?

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..
