Answers:

Directions (Q.1-5):

  1. Answer b

(7/4)*(2/28)*(8/9)*567 = x

X = 63

  1. Answer a

(560 ÷ 32) × (720 ÷ 48) = x

X = (560/32) × (720/48)

X = 525/2 = 262.5

  1. Answer d

(48/100)*4800 + (24/100)*1620 = x

X = 2304 + 388.8

X = 2692.8

  1. Answer c

3 ½ + 4 ¼ + 9 ¾ + 6 7/8 = x + 5 ¾ × 2 ¼

3 ½ + 4 ¼ + 9 ¾ + 6 7/8 = x + 12 15/16

3 ½ + 4 ¼ + 9 ¾ + 6 7/8 – 12 15/16 = x

(3 + 4 + 9 + 6 -12) (½ + ½ + ¾ + 7/8 – 15/16) = x

10 ((8+4+12+14-15)/16) = x

X = 10 (23/16) = 11 (7/16)

  1. Answer b

√7056 ÷ 3 + √12544 = 25x

25x = (84/3) + 112

25x = 28 + 112

25x = 140

X = (140/25) = 5.6

Directions (Q. 6 – 10):

  1. Answer d

The difference of the following series is 4, 8, 4, 8…

The answer is, 38

  1. Answer b

The pattern is, *1/2, *2/3, *3/4, *4/5, *5/6,..

The answer is, 31.2

  1. Answer c

The pattern is, ÷ 8, ÷ 6, ÷ 4, ÷ 2

The answer is, 4.5

  1. Answer a

The difference of difference is, 8, 16, 24, 32,..

The answer is, 302

  1. Answer b

The pattern is, *1 + 5, *2 + 5, *3 + 5, *4 + 5…

The answer is, 1093

 

  1. Answer d

200000*(60/100) = 120000

200000*(64/100)*(96/100) = 122880

The difference is,

= > 122880 – 120000

= >2880

  1. Answer b

Πr2 + lb = 991

(22/7)*14*14 + 25b = 991

616 + 25b = 991

25b = 991 – 616

25b = 375

=>b = 15 cm

Circumference of circle = 2πr = 2*(22/7)*14 = 88 cm

Perimeter of rectangle = 2(l + b) = 2(25 + 15)

= > 2 * 40 = 80 cm

Required answer = 88 + 80 = 168 cm

  1. Answer c

Ratio of share of Sree and Subha is,

= > [30000*4 + 20000*8]: [40000*4 + 50000*8]

= > 280000: 560000

= > 1: 2

Total profit = Rs. 36000

3’s = 36000

1’s = 12000

Share of Subha = 2’s = Rs. 24000

  1. Answer b

Salary*(60/100)*(75/100)*(65/100) = 58500

Salary = 58500*(100/60)*(100/75)*(100/65) = 200000

Spending on food = 200000 * (40/100) = 80000

Spending on clothes = 200000 * (60/100) * (25/100) = 30000

Sum of spending on food and cloth together = 80000 + 30000 = 110000

Average = 110000/2 = Rs. 55000

  1. Answer a

Total probability = 15C3

Required probability = 6C2 and 9C1

The probability that 2 marbles are pink,

= > [6C2 and 9C1] / 15C3­

= > (15*9) / (5*7*13)

= > 27/91

 

Directions (Q. 16 – 20):

  1. Answer b

Required % = [(135/6)/(200/6)] x 100 = 67.5%

  1. Answer a

Let the expenditure was x lakhs

So, 50 = (30-x/x) * 100

150x = 3000

x = 20 lakhs

  1. Answer b

In 2006, fall % = (10/20)*100 = 50 %

In 2007, rise % = (25/10) * 100 = 250 %

In 2008, fall % = (5/35)*100 = 14.28 %

In 2009, rise % = (25/30)*100 = 83.33 %

In 2010, fall % = (25/30)*100 = 45.45 %

  1. Answer c

Required % = (50-45)/45 x 100 = 11.11% ≈ 11%

  1. Answer d

Required % profit = [(35-15)/15] x 100 = 133.33%
