  2. 12%

  4. 14%
  5. 15%

Answers:

  1. Answer b

The average score of 45 students = 78

Total score of 45 students = 45*78 = 3810

If the last five students are removed, the average drops by 5 marks.

So,

The average score of 40 students = 73

Total score of 40 students = 40*73 = 2920

X+ (x+1) + (x+2) + (x+3) + (x+4) = 590

5x + 10 = 590

5x = 580

X = 116

Least score = 116

  1. Answer d

According to the question,

(16/24) + (x/27) =1

(2/3) + (x/27) =1

(X/27) =1 – (2/3)

(x/27) =1/3

X= 9 days

  1. Answer b

Population = 360000 × 106/100 × 92/100 =351072

  1. Answer a

Raja’s score = 456 marks, Seema = 54 % of total = Raja’s score – 24

Seema = 456-24 = 432 = 54% of total marks

(54/100)*x = 432

X = 432*(100/54) = 800

Minimum passing marks = 34 % of total marks

= > (34/100)*800 = 272

Raja scores 184 marks more than the passing marks.

  1. Answer c

Let the present age of these two persons are ‘x’ & ‘y’

(x + y)/2 = 52

x + y = 104 –à (1)

(x – 16)/(y – 16) = 1/2

2x – 32 = y – 16

2x – y = 16–à (2)

By solving the equation (1) and (2), we get,

x = 40 years and y = 64 years

Difference = 64 – 40 = 24 years

 

Directions (Q. 6-10):

  1. Answer a

(8/15) of (3/17) of (12/13) of 15470= X

X= (8/15)*(3/17)*(12/13)*15470

X= 1344

  1. Answer c

(26)2 × 6 ÷ 13 + 53 + 88 = x3 -204

(26*26*6)/13 +125 +88 = x3 -204

312 +125 +88 +204 = x3

X3 = 729

X= 9

  1. Answer d

(26 × 14 × 432) / 54 = x + 728

2912 -728 = x

X = 2184

  1. Answer c

5 7/8 + 9 3/16 – 7 4/9 – 3 2/3 = x

(5+9 -7-3) (7/8 + 3/16 – 4/9 – 2/3) =x

4 [(126+27 -64-96)/144] =x

X= 4 (-7/144) = 569/144

X = 3 137/144

  1. Answer b

136% of 105 – 84% of 165 = X

142.8 – 138.6 =X

X= 4.2

 

Directions (Q. 11-15):

  1. Answer a

The pattern is, ÷ 1 × 3, ÷ 2 × 6, ÷ 3 × 9, ÷ 4 × 12

The answer is, 1458

(Or)

The series follows *3, *3, *3….

  1. Answer d

The pattern is, difference of 2 numbers /2

The answer is, 1556

  1. Answer b

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

The answer is, 1088

  1. Answer c

The pattern is, +7, -11, +13, -17, +19

The answer is, 783

  1. Answer e

The pattern is, *2 + 12, *3 + 32, *4 + 52, *5 + 72

The answer is, 457

 

Directions (Q. 16-20):

  1. Answer c

Total production of cement by the companies A and D in year 1994

= 50 + 35 = 85

The companies E and G in year 1994 = 22 + 63 = 85

Hence, year 1994 in the answer

  1. Answer d

The average production of G in all the years

= > 32 + 37 + 52 + 63 + 80 + 120 +123 + 129 = 636

The average production of C in all the years

= > 78 + 69 + 63 + 70 + 72 + 59 + 81 + 65 = 557

Required % = (636/557)*100 = 114. 18 % ≈ 114 %

  1. Answer b

From table

It is shown, clearly that company E & G have shown continuous growth in production

  1. Answer a

The total production of B, D and E in the year 1994,

= > 23 + 35 +22 = 80

The total production of A, C and F in the year 1998,

= > 63 + 65 + 80 = 208

Required Ratio = 80: 208

= > 5: 13

  1. Answer a

Required percentage = (391 – 351)/351 = 40/351 x 100 = 11.4% ≈ 11%
