Answers:

Directions (Q. 1-5):

  1. Answer d

2704 + (34/100)*700 – (4/5)*5060 = x – 3375

2704 + 238 – 4048 + 3375 =x

X= 2269

  1. Answer a

(12-5+3+7) (3/4 – 2/5 +1/8 +1/2) = x

X = 17((30-16+5+20)/40)

X = 17 39/40

  1. Answer c

X = 770/22 + 135 – (12/100)*560

X = 35 +135 – 67.2

X = 102.8

  1. Answer b

(144-104)/ (64+19+441) = x

X= 40/524

X = 10/131

  1. Answer d

(7/2)*828 + (58/100)*440 + (21/8)*(18/63) = x

X = 2898 + 255.2 + 0.75

X = 3153.95

 

Directions (Q. 6-10):

  1. Answer b

The pattern is, 5*Prime no (Prime no Start with 2)

The answer is, 85

  1. Answer a

The pattern is, *1+13, *2+23, *3+ 33, *4+43, *5+53….

The answer is, 4705

  1. Answer c

The pattern is, ÷4 +3

The answer is, 5.25

  1. Answer a

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

The answer is, 13

  1. Answer d

The pattern is, *2 +3, *3 -4, *4+5, *5 -6….

The answer is, 2279

 

  1. Answer b

The ratio of Profit of A, B and C,

= > [15000*3 + 15000*(1/3)*9] : [20000*3 + 25000*9] : [30000*6]

= > 90000: 285000: 180000

= > 6:19:12

Total Profit = Rs. 55500

B’s share = (55500/37)*19 =Rs. 28500

  1. Answer c

Radius = (2/3)*side

Area of square = a2 = 441

Side (a) = 21 cm

Radius = (2/3)*21 = 14 cm

Perimeter of the circle = 2πr

= > 2*(22/7)*14

= > 88 cm

  1. Answer a

Let two numbers be x and y,

X + Y= 3420

12% of one number = 28 % of another number

(12/100)*x = (28/100)*y

x/y = 28/12 = 7/3

x : y = 7 : 3

10’s = 3420

1’s = 342

Largest number = 7’s = 342*7 = 2394

  1. Answer c

4 years ago, Mother: Son = 4: 1 <= (4x, x)

After 6 years, M: S =5: 2

According to the question,

4x + 10/ x+10 = 5/2

8x + 20 = 5x + 50

3x = 30

X = 10

Present ages of mother and son = (4x+4, x+4) = 44, 14

After 13 years, Ratio of mother and son = (44+13, 14+13)

= > 57: 27 = 19: 9

  1. Answer b

Three pipes A, B and C can fill a tank in 8 hours.

A, B and C’s 1 hour work=1/8

A, B and C’s 3 hour work= 3/8

Remaining work= 1-3/8 =5/8

The remaining part will be filled by A and B in 6 hours. Then,

= > (5/8) *(A+B) = 6

= > (A+B)’s whole work= 48/5 hr

(A+B)’s 1 hour work= 5/48

A, B and C’s 1 hour work=1/8

C’s 1 hour work= (A+B+C)-(A+B)

= > (1/8) – (5/48)

= > 1/48

C can fill the tank in 48 hours.

 

Directions (Q. 16 – 20):

  1. Answer b

Failed students of college x in 2006 = 400*(50/100) =200

Failed students of college x in 2006 is 25% more than the passing student in college x in 2010,

200 = (125/100)* Passing students of college x in 2010

Passing students of college x in 2010 = 200*(100/125) = 160

(40/100)* total students = 160

Total students = 160*(100/40) = 400

Failed students of college X in 2010 = 400*(60/100) = 240

  1. Answer d

Total no of students of College X and Y in 2010, is not given. So we can’t find the passing student in those colleges.

  1. Answer b

Passed students of college x in 2006 =50% of 400 =200

Passed students of college x in 2008 = 60% of 250 =150

Difference =200 – 150 =50

  1. Answer b

passed students of college y in 2006 = 40% 0f 450 = 180

passed students of college y in 2009= 120% 0f 180 = 216

pass % = (216/600) x 100 = 36%

  1. Answer e

pass male=150

so, pass female =120

total pass students =270

45% = 270

1% = 6

100% =600
