Question No 1

It was Sunday on Jan 1, 2006.What was the day of the week Jan 1, 2010?

Select the correct answer


Solution!
On 31st December, 2005 it was Saturday.
Number of odd days from the year 2006 to the year 2009 = (1 + 1 + 2 + 1) = 5 days.

So, On 31st December 2009, it was Thursday.

Thus, on 1st Jan, 2010 it is Friday..

Question No 2

January 1, 2008 is Tuesday.What day of the week lies on Jan 1, 2009?

Select the correct answer


Solution!
The year 2008 is a leap year. So, it has 2 odd days.

1st day of the year 2008 is Tuesday (Given)

So, 1st day of the year 2009 is 2 days beyond Tuesday.

Hence, it will be Thursday..

Question No 3

Speed of water in certain river is 6 km/h and it takes a boat four times as long to row up as to row down the river. What is the speed of boat in still water?

Select the correct answer


Solution!
Let speed of boat in still water is x.
Speed of water = v = 6 Km/h
As downstream speed is four times the upstream speed so

(x+6) = 4(x-6)
x+6 = 4x-24
30 = 3x
x = 10

Hence speed of boat in still water is 10 Km/h.

Question No 4

A train running at the speed of 60 km/hr crosses a pole in 9 seconds.What is the length of the train?

Select the correct answer


Solution!
Speed = 60 * (5/18) = 50/3 m/sec

Length of the train = (Speed x Time) = (50/3) * 9 = 150 meters.

Question No 5

The difference of the ages of two brothers is 2 and the difference of the square of their ages is 16. The age of smaller one is?

Select the correct answer


Solution!
Let present age of elder brother is y and present age of younger brother is x.

Given that
y-x = 2 ...(1)

and
(y^2)-(x^2) = 16
(y+x)(y-x) = 16

Put value of (y-x) from equation(1)
2(y+x) = 16
y+x = 8 ...(2)

By simultaneously solving equation(1) and equation(2) we have
y = 5
and
x = 3

Hence present age of younger brother is 3 years..

Question No 6

What is the angle between the hands of a clock at 1 o'clock?

Select the correct answer


Solution!
At 1 o'clock the minute hand points to the 12 and the hour hand points to the 1.

So we need to find the angle between the 12 and the 1.

There are 12 total numbers on the clock and total angle on complete turn of the clock is 360 degree, so each one must be 360/12 = 30 degree.

So the angle between the hands of a clock at 1 o'clock is 30 degree..

Question No 7

Two trains are running in opposite directions with the same speed. If the length of each train is 120 metres and they cross each other in 12 seconds, then the speed of each train is

Select the correct answer


Solution!
Let the speed of each train be x m/sec.

Then, relative speed of the two trains = 2x m/sec.

So, 2x = (120 + 120)/12
2x = 20
x = 10

Hence, Speed of each train = 10 m/sec = 10 * (18/5)
= 36 km/hr.

Question No 8

A person's present age is two-fifth of the age of his mother. After 8 years, he will be one-half of the age of his mother. How old is the mother at present?

Select the correct answer


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

Then,
the person's present age = (2/5)x years.

(2/5)x + 8 = (1/2)(x + 8)
2(2x + 40) = 5(x + 8)
x = 40
.

Question No 9

What is 35% of 250?

Select the correct answer


Solution!
35 * (250/100) = 87.5

Quick way to find answer from options is

33% of 250 is nearly 83(250/3 = 83.3)

So, answer should be in 80's which is only one option 87.5.

Question No 10

Question No 13

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..

Question No 19

Two trains are moving in opposite directions at speed of 60 km/hr and 90 km/hr. Their lengths are 1.10 km and 0.9 km respectively. The time taken by the slower train to cross the faster train is

Select the correct answer


Solution!
Relative speed = (60+ 90) km/hr
= 150 * (5/18)m/s
= (125/3)m/s

Distance covered = (1.10 + 0.9) km = 2 km = 2000 m

Hence, Required time = 2000(3/125) = 48 seconds.

Question No 20

Question No 21

Speed of water in certain river is 2 km/h and it takes a boat thrice as long to row up as to row down the river. Find the speed of the boat in still water.

Select the correct answer


Solution!
Let speed of boat in still water is x.
Speed of water = v = 2 Km/h

As downstream speed in 3 times the upstream speed so
(x+2) = 3(x-2)
x+2 = 3x-6
8 = 2x
x = 4
Hence speed of boat in still water is 4 Km/h.

Question No 22

N - C = N is the sister of C

and C + F = C is the brother of F.

Hence, M is the father of C or C is the son of M..

Question No 23

A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?

Select the correct answer


Solution!
Speed = 72 * (5/18)m/s
= 20 m/s

Time = 26 sec

Let,
the length of the train be x metres

Then,
(x+250)/26 = 20

x + 250 = 520
x = 270.

An article was sold at a loss of 15% for $476. What is the cost price of the article?

Select the correct answer


Solution!
Let cost price of the article is x.
15% of x = (15x)/100 = 3x/20

Now
(3x/20) + 476 = x
3x+9520 = 20x
9520 = 17x
x = 560

Hence cost price of the article is $560..

Question No 30

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 31

A mother's age after 5 years, will be twice the age of her daughter. The difference of their ages is 19. What is the age of mother?

Select the correct answer


Solution!
Let present age of daughter is x and present age of mother is y.

Given that
y+5 = 2(x+5)
y+5 = 2x+10
5-10 = 2x-y
y-2x = 5 ...(1)

and also given that
y-x = 19 ...(2)

By simultaneously solving equation(1) and equation(2) we can find
y = 33

Hence mothers present age is 33 years..

Question No 32

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..

Question No 38

A train of length 150 metres is running at the speed of 20m/s. In what time will it cross a 130 metre long bridge?

Select the correct answer


Solution!
Length of the train = L1 = 150m
Length of bridge = L2 = 130m
Speed = v = 20m/s

t = (L1 + L2)/v
t = (150+130)/20
t = 14

Hence the train will pass the 130 meter long bridge in 14 seconds..

Given that
A/B = 3/2
2A = 3B
2A-3B = 0 ...(1)

and also given that
(A-10)/(B+10) = 2/3
3A-30 = 2B+20
3A-2B = 50 ...(2)

By simultaneously solving equation(1) and equation(2)
A = 30

Hence age of A is 30 years..

Time is 2.20.
Hour hand at 2 (nearly) and minute hand at 4.

Angle between 2 and 4 is 60 degrees [(360/12) * (4-2)]

Angle made by the hour hand in 20 minutes is 10 degrees, since it turns through 1/2 degrees in a minute.

Therefore, angle between the hands is 60 degrees - 10 degrees = 50 degrees.

10 women can complete a work in 7 days and 10 children take 14 days to complete the work.How many days will 5 women and 10 children take to complete the work?

Select the correct answer


Solution!
1 woman's 1 day's work =1/70

1 child's 1 day's work =1/140

(5 women + 10 children)'s 1 day's work = (5/70 + 10/140) = (1/14 + 1/14) = 1/7

Hence, 5 women and 10 children will complete the work in 7 days..

Question No 60

A is 30% more efficient than B. How much time will they, working together, take to complete a job which A alone could have done in 23 days?

Select the correct answer


Solution!
Ratio of times taken by A and B = 100/130 = 10/13

Suppose B takes x days to do the work.

Then, 10/13 = 23/x
x = (23*13)/10
x = 299/10

A's 1 day's work = 1/23

B's 1 day's work = 10/299

(A + B)'s 1 day's work = (1/23 + 10/299) = 23/299 = 1/13

Therefore, A and B together can complete the work in 13 days..
