Answers :

Direction (1-5) :

1) Answer: c)

The total number of readers of the state AP in the year 2015 = 57200

(22/100)*total number of readers in the year 2015 = 57200

Total number of readers in the year 2015 = 57200*(100/22) = 260000

The total number of readers of the state AP in the year 2016 = 45600

(19/100)*total number of readers in the year 2016 = 45600

Total number of readers in the year 2016 = 45600*(100/19) = 240000

Total number of readers of the state Kerala in the year 2015

= > 260000*(24/100) = 62400

Total number of readers of the state Kerala in the year 2016

= > 240000*(27/100) = 64800

Required difference = 64800 – 62400 = 2400

2) Answer: a)

The ratio of total number of readers of the state AP in the year 2016 to that of the state MP in the year 2015 = 4 : 5(4x, 5x)

Total number of readers in the year 2016 = 4x*(100/19) = 400x/19

Total number of readers in the year 2015 = 5x*(100/18) = 250x/9

Required ratio = (400x/19) : (250x/9) = 72 : 95

3) Answer: d)

The total number of readers of all the given states together in the year 2015 = 24 lakhs

The total number of readers of MP in the year 2015 = 24*(18/100) = 4.32 lakhs

The total number of readers of all the given states together in the year 2016 = 28 lakhs

The total number of readers of MP in the year 2016 = 28*(21/100) = 5.88 lakhs

Required sum = 4.32 + 5.88 = 10.2 lakhs

4) Answer: b)

Required % = (19/18)*100 = 105.55 % = 106 %

5) Answer: d)

Total number of readers of state Kerala in the year 2015 = 84000

Total number of readers of state AP in the year 2015

= > 84000*(100/24)*(22/100)

= > 77000

Total number of readers of state MP in the year 2016 = 52500

Total number of readers of state Kerala in the year 2016

= > 52500*(100/21)*(27/100)

= > 67500

Required ratio = 77000 : 67500 = 154 : 135

Direction (6-10) :

6) Answer: a)

3x – 5y = 61 –à (1)

2x – 3y = 38 –à (2)

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

X = 7, y = -8

X > y

7) Answer: c)

I) x3 × 19 = x2 × 361

X3 ÷ x2 = 361/19

x = 19

II) y1/3 × 17 = 357 ÷ y2/3

Y1/3 × y2/3 = 357/17

Y3/3 = 21

y = 21

x < y

8) Answer: e)

I) 4x2 – √2x – 3 = 0

4x2 – 3√2x + 2√2x – 3 = 0

√2x (2√2x – 3) + 1(2√2x – 3) = 0

(√2x + 1) (2√2x – 3) = 0

x = -1/√2, 3/(2√2) = -0.707, 1.06

II) 5y2 – √5y – 2 = 0

5y2 – 2√5y + √5y – 2 = 0

√5y (√5y – 2) + 1(√5y – 2) = 0

(√5y + 1) (√5y – 2) = 0

y = -1/√5, 2/√5 = -0.448, 0.89

Can’t be determined

9) Answer: a)

I) √(x + 4) = √676 – √361

√(x + 4) = 26 – 19

(x + 4) = 72

X = 49 – 4 = 45

II) y3 – 32568 = 26751

Y3 = 26751 + 32568

Y3 = 59319

Y = ∛59319 = 39

X > y

10) Answer: e)

I) 4x2+ 20x + 24 = 0

4x2 + 8x + 12x + 24 = 0

4x(x + 2) + 12(x + 2) = 0

(4x + 12) (x + 2) = 0

X = -3, -2

II) 16y2 + 67y + 12 = 0

16y2 + 64y + 3y + 12 = 0

16y (y + 4) + 3 (y + 4) = 0

(16y + 3) (y + 4) = 0

Y = -3/16, -4

Can’t be determined
