QUESTION: 1

A father is 30 times older than his son. 18 years later, he will be only thrice as old as his son. Father's present age in years is

A.
25
B.
30
C.
40
D.
45

Solution:

F = 30 S
or, S = F/ 30
Also, F + 18 = 3(S + 18)
∴ F + 18 = 3( F/ 30 + 18)
or, F + 18 = F /10 + 54
or, F - F /10 = 36 or, 9 /10 F = 36
or, F = 36 x 10 /9 = 40 yrs

QUESTION: 2

Rajneetha walks around the circular park in 15 minutes. If she walks at the rate of 5 km/hr, how much distance would she have to travel, at the minimum, to reach the centre of the park from any point on its perimeter?

A.
100 metre
B.
200 metre
C.
250 metre
D.
300 metre

Solution:

Time = 15 minutes
= 15 x 60 sec = 900 sec
Speed = 5 km/hr
= 5 x 5/ 18 m/sec
= 25 18 m/sec
Now Perimeter of the circular park = D
= S x T
= 25/ 18 x 900
2πR = 1250 metre
R = 1250 x 7 /2x 22 = 8750/ 44
= 198.86 metres
∴ Required minimum distance to reach the centre of the circle = 200 metre (approx)

QUESTION: 7

An anti aircraft gun can fire four shots at a time. If the probabilities of the first, second, third and the last shot hitting the enemy aircraft are 0.7, 0.6, 0.5 and 0.4, what is the probability that four shots aimed at an enemy aircraft will bring the aircraft down?

A.
0.084
B.
0.916
C.
0.036
D.
0.964

Solution:

The enemy aircraft will be brought down even if one of the four shots hits the aircraft.
The opposite of this situation is that none of the four shots hit the aircraft.
The probability that none of the four shots hit the aircraft is given by:
(1 − 0.7)(1 − 0.6)(1 − 0.5)(1 − 0.4) = 0.3 x 0.4 x 0.5 x 0.6 = 0.036
So, the probability that at least one of the four hits the aircraft:
= 1 – 0.036 = 0.964

QUESTION: 9

If a:b=c:d=e:f=1:2, then (pa+qc+re):(pb+qd+rf) is equal to

A.
p:(q+r)
B.
(p+q):r
C.
2:3
D.
1:2

Solution:

a : b = c : d = e : f = 1 : 2 = k
a = k, b = 2k, c = k, d = 2k, e = k, f = 2k
pa + qc + re = pk + qk + rk
= k (p + q + r)
pb + qd + rf = p x 2k + qx 2k + r x 2k
= 2k(p + q + r)
∴ (pa + qc + re) : (pb + qd + rf)
= k(p + q + r) : 2k(p + q + r)
= 1: 2

QUESTION: 10

Mr. Anuraag Awasthi deposits an amount of Rs 56500 to obtain a simple interest at the rate of 12 p.c.p.a. for 3 years. What total amout will Mr. Anurrag Awasthi get at the end of 3 years ?

A.
Rs 75680
B.
Rs 77540
C.

Solution:

SI = P x R x T 100
⇒ SI = 56500 x 12 x 3 100
⇒ SI = Rs 20,340
⇒ Amount = Principle + SI
⇒ Amount = Rs (56500 + 20340) = Rs 76840

QUESTION: 12

How many metres of cloth 1.1m wide will be required to make a conical tent whose vertical height is 12m and base radius is 16m?

A.
914 2 7 m
B.
917m
C.
91.4m
D.
917.05m

Solution:

Radius of cone, r = 16m
Height of cone, h = 12m
Slant height of cone = l = h 2 + r 2
= 12 2 + 16 2 = 144 + 256 = 400 = 20 m
Area of cloth required = Lateral surface area of the cone = πrl
= 22 7 x 16 x 20 = 7040 7 sq.m
Width of the cloth = 1.1m
∴ Length of the cloth = Area Width = 7040 x 10 7 x11 = 6400 7 = 914 2 7 metres

QUESTION: 13

In each of the following questions, two equations are given. You have to solve these equations and

2. I. x² - 24x + 144 = 0
II. y² - 26y + 169 = 0

A.
x < y
B.
x > y
C.
x = y
D.
x ≥ y
E.
x ≤ y

Solution:

I. x² - 24x + 144 = 0
⇒ x² - 12x - 12x + 144 = 0
⇒ x(x - 12) - 12 (x - 12) = 0
⇒ (x - 12) (x - 12) = 0
⇒ x = 12
II. y² - 26y + 169 = 0
⇒ (y - 13)² = 0
⇒ y - 13 = 0
⇒ y = 13
x < y

QUESTION: 14

In each of the following questions, two equations are given. You have to solve these equations and

I. 2x² + 3x - 20 = 0
II. 2y² + 19y + 44 = 0

A.
x < y
B.
x > y
C.
x = y
D.
x ≥ y
E.
x ≤ y

Solution:

I. 2x² + 3x - 20 = 0
⇒ 2x² + 8x - 5x - 20 = 0
⇒ 2x (x + 4) - 5 (x + 4) = 0
⇒ (x + 4) (2x - 5) = 0
⇒ x = -4 or 5252
II. 2y² + 19y + 44 = 0
⇒ 2y² + 11y + 8y + 44 = 0
⇒ y(2y + 11) + 4 (2y + 11) = 0
⇒ (y + 4) (2y + 11) = 0
⇒ y = -4 or -112112
x ≥ y

QUESTION: 15

These questions are based on the graph which shows the Demand and Production statistics of the five companies.

What is the ratio of companies having more demand than production to those having more production than demand?

A.
2:3
B.
4:1
C.
2:2
D.
3:2

Solution:

What is the difference between the average demand and the average production of five companies taken together ?

A.
1400
B.
400
C.
280
D.
138

Solution:

Avg Demand = (3000 +600+2500+1200+3300)/5=10600/5 = 2120
Avg Production = 1840
So the Diff is 280

Percentage break up of student in each discipline

Which discipline has the highest number of boys studying in it ?

A.
Science
B.
Commerce
C.
Arts
D.
Management
E.
None of these

Solution:

Number of boys in Science discipline
= 4800 � 37/100 - 2000 � 32/100
= 1776 - 640 = 1136
Number of boys in Commerce discipline
= 4800 � 21/100 - 2000 � 24/100
= 1008 - 480 = 528
Number of boys in Arts discipline
= 4800 � 18/100 - 2000 � 14/100
= 864 - 280 = 584
Number of boys in Management discipline
= 4800 � 10/100 - 2000 � 8/100
= 480 - 160 = 320
Hence, highest number of boys are studying in Science discipline.

QUESTION: 19

The following table gives the tariff [in paise per kilo-watt-hour (k Wh)] levied by the UPSEB in 1994-95, in four sectors and the regions within them. The table also gives the percentage change in the tariff as compared to 1991-92.

The UPSEB supplies power under four categories; urban (25%), domestic (20%), industrial (40%), and rural (15%). In 1994-95, the total power produced by the UPSEB was 7875 megawatts.

If in 1994-95, there was a 10% decrease in the domestic consumption of powers as compared to that in 1991-92, what was the consumption of power in the rural sector in 1991-92?

A.
1,312 megawatt
B.
1,422 megawatt
C.
1,750 megawatt
D.
1,500 megawatt
E.
None of these

Solution:

The domestic consumption in 1991-92 = 1,575/0.9 = 1,750 megawatts.
This constitutes 20% of total power consumed in 91-92 and the rural consumption constitutes 15% of total power in 91-92
Hence in 1991-92, the rural consumption = (1,750 � 15201520) = 1,312 megawatts

QUESTION: 20
