Question No 2

A's age is 3/4 of that of B's. Two years ago A's age was 1/2 of what B will be in 4 years. How old is A now?

Select the correct answer

17 12 20 25

Solution!
Given that
A = (3/4)B ...(1)

and
A-2 = (1/2)(B+4)
2A-4 = B+4
2A-B = 8

Put value of B from equation(1)
2A-(4/3)A = 8
6A-4A = 24
2A = 24
A = 12

Hence A is 12 years old now..

Question No 3

At 3:40, the hour hand and the minute hand of a clock form an angle of ...

Select the correct answer

120 degree 125 degree 130 degree 135 degree

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

Angle traced by it in 11/3 hrs = (360/12 * 11/3) = 110 degree

Angle traced by minute hand in 60 min. = 360 degree

Angle traced by it in 40 min = (360/60 * 40) = 240 degree

So, Required angle (240 - 110) = 130 degree.

Question No 4

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

1 km/h 2 km/h 0.5 km/h 0.25 km/h

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.

Question No 5

100 oranges are bought at the rate of Rs. 350 and sold at the rate of Rs. 48 per dozen.The percentage of profit or loss is

Select the correct answer

100/7 % gain 100/7 % loss 15 % gain 15 % loss

Solution!
C.P. of 1 orange = 350/100 = Rs. 3.50

S.P. of 1 orange = 48/12 = Rs. 4

Hence, Gain% = (0.50)/(3.50) * 100 = 100/7 %.

Question No 6

The length of the bridge, which a train 130 metres long and travelling at 45 km/hr can cross in 30 seconds, is

Select the correct answer

200 m 225 m 245 m 250 m

Solution!
Speed = 45 * (5/18)
= 25/2 m/s

Time = 30 sec

Let the length of bridge be x metres

Then,
(130 + x)/30 = 25/2
2(130 + x) = 750

Hence, x = 245 m.

Question No 7

Solution!
As
M + 2 = O
A + 2 = C
S + 2 = U
T + 2 = V
E + 2 = G
R + 2 = T

Similarly
L + 2 = N
A + 2 = C
B + 2 = D
O + 2 = Q
U + 2 = W
R + 2 = T
.

Question No 11

9 excavators working 10 hours a day remove 2500 cubic feet of earth in 3 days. How many excavators working 6 hours a day are required to remove 5000 cubic feet of earth in 2 days?

Select the correct answer

55 50 45 40

Solution!
Let x excavators are required.
As excavators are inversely proportional to hours and days and directly proportional to work progress so
x/9 = (10/6)*(5000/2500)*(3/2)
x = 45

Hence 45 excavators are required to remove 5000 cubic feet of earth..

Question No 12

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

65 70 35 55

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..
