Answers:

Directions (Q. 1-5):

  1. Answer a

√((36 ÷3)×(x ÷3)) = 7.2 ÷ 6 + 0.3

√(4x) = 1.2+0.3

2√x = 1.5

√x = 1.5/2 = 0.75

X = 0.5625

  1. Answer c

(16*16*10-14)  ÷ (32 × 23 × 10-3) = 10x

10-14+3 = 10x

X = -11

  1. Answer b

2197 ÷ 13 ÷ 2 × 18 + 48 % of 550 + 62 % of 1700 = x

1521 + (48/100)*550 + (62/100)*1700 = x

X = 1521 + 264 + 1054

X = 2839

  1. Answer d

(1.6)x-3 = (1.6)10 ÷ (4.096)3 × (1.6)7

(1.6)x-3 = (1.6)10 ÷ (1.6)9 × (1.6)7

(1.6)x-3 = 1.610-9+7

(1.6)x-3 = 1.68

x-3 = 8

x = 11

  1. Answer e

(75/100)* (2/17) * (51/147) * (2/5) * 38465 = x

X = 471

Directions (Q. 6 – 10):

  1. Answer d

The pattern is, *5 – 1, *5 -2, *5 -3, *5 -4,..

The answer is, 9831

  1. Answer b

The pattern is, +17, -34, +51, -68, +85,..

The answer is, 272

  1. Answer c

The pattern is, *0.5 + 1, *1 + 2, *2 + 3, *4 + 4, *8 + 5,..

The answer is, 2757

  1. Answer e

The pattern is, +32, +43, +52, +63, +72, +83,..

The answer is, 902

  1. Answer c

The pattern is, ÷ 4 + 4, × 4 + 4(alternatively)

The answer is, 63

 

  1. Answer b

Let the numbers be 4 x, 7x and 12 x

4x+12x-7x= 144

x = 16

The largest number is 12 * 16= 192

  1. Answer a

Total age of all the members in the family= 30*5= 150 years

Total age of the four members at the time of birth of youngest= 150- 10*5= 100 years.

Required average of family= 100/4= 25 years.

  1. Answer d

Area of a circle= πr2

5544= 22r2/7

5544*7/22= r2

r2= 1764

r= 42m

Circumference = 2*22/7 * 42= 264 sq. m

Perimeter of the rectangle= 132 sq. m

132= 2(l + 10)

132= 2l+20

L= 112/2

L= 56

Area of the rectangle = 56*10= 560 sq. m

  1. Answer b

Raghu’s monthly income is (5/4) times that of Raju’s income,

= > Income of Raghu and Raju =5 : 4(5x, 4x)

Expense ratio = 2 : 1

Savings are, 12000 and 12000

(5x-12000) / (4x-12000) = 2/1

5x- 12000 = 8x – 24000

3x = 12000

X = 4000

Raju’s monthly income = 4x = 4*4000  = 16000

Annual income = 16000*12 = Rs. 192000

  1. Answer c

Let the length of the train A be x and speed be y

40= (x + x)/y

40y= 2x

x= 20y

Now,

100= (1320+x)/y

100y= 1320 + x

Putting the value of x

100y= 1320+ 20y

80y= 1320

Speed = y= 16.5 m/s

Train length = x = 20y = 20*16.5

= > 330 m

 

Directions (Q. 16 – 20):

  1. Answer c

Total number of units manufactured by Company C

= 2.6 + 2.2 + 2.1 + 2.8 + 2.6 = 12.3 = 12.3 x 100

= 1230

  1. Answer e

% increase = (1.7 – 1.4)/1.4 x 100 = 0.3/1.4 x 100 = 21 (approx.)

  1. Answer d

Required percentage = 2.2/3 x 100 = 73.33

  1. Answer e

Required Ratio = 3.4 : 1.7 = 2 : 1

  1. Answer b

Total number of units sold by Company D over all the years

= 2.2 + 1.9 + 1.5 + 1.2 + 1.1 = 7.9

Required Average = (7.9 x 100)/5 = 790/5 = 158
