e) None of these

Answers :

1) Answer: e)

I) x2 – 5√7 x + 42 = 0

(x – 2√7) (x – 3√7) = 0

X = 2√7, 3√7 = 5.29, 7.93

II) y2 + 3√2 y – 56 = 0

(y – 4√2) (y + 7√2) = 0

Y = 4√2, -7√2 = 5.656, -9.898

Can’t be determined

2) Answer: c)

I. √361 x + √9025 = 0

19x + 95 = 0

19x = -95

x = – 5

II. (7776)1/5 y + (13824)1/3 = 0

(65)1/5 + (243)1/3 = 0

6y + 24 = 0

6y = -24

Y = -4

X < y

3) Answer: e)

I) (x8/5 ÷ 25) = (64 ÷ x2/5)

X8/5 × x2/5 = 64 × 25

X10/5 = 64 × 25

X2 = 64 × 25

X = + (8*5), – (8*5) = +40, -40

II) y2/9 × y7/9 × 36 = 216 × y1/2

Y2/9 + 7/9 – ½ = 216/36

Y1/2 = 6

Y = 36

Can’t be determined

4) Answer: e)

I) 13x2 – 16x – 32 = 8x2 – 28x

5x2 + 12x – 32 = 0

5x2 + 20x – 8x – 32 = 0

5x (x + 4) – 8(x + 4) = 0

(5x – 8) (x + 4) = 0

X = 8/5, -4 = 1.6, -4

II) 17y2 + 22y + 9 = 13y2 + 10y

4y2 + 12y + 9 = 0

4y2 + 6y + 6y + 9 = 0

2y(2y + 3) + 3(2y + 3) = 0

(2y + 3) (2y + 3) = 0

Y = -3/2, -3/2 = -1.5, -1.5

Can’t be determined

5) Answer: c)

I) 3x + 5y = √2025

3x + 5y = 45 –à (1)

II) 2x + 3y = ∛21952

2x + 3y = 28 –à (2)

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

X = 5, y = 6

X < y

Direction (6-10) :

6) Answer: a)

The total female population in below poverty line in state A = 81.6 lakhs

The ratio between the total male to that of female population of below poverty line in state A

= > 1 : 2

2’s = 81.6

1’s = 40.8

Total population of below poverty line in state A

= > 81.6 + 40.8 = 122.4 lakhs

34 % of total population in state A = 122.4

Total population in state A = 122.4*(100/34) = 360 lakhs

7) Answer: c)

The total male population in above poverty line in state C = 224.64 lakhs

The ratio between the total male to that of female population of above poverty line in state C = 8: 7

8’s = 224.64

1’s = 28.08

The total female population of above poverty line in state C = 196.56 lakhs

The total population of above poverty line in state C

= > 224.64 + 196.56 = 421.2 lakhs

78 % of total population in state C = 421.2 lakhs

Total population of below poverty line in state C

= > 421.2*(100/78)*(22/100) = 118.8 lakhs

The total male population of below poverty line in state C

= > 118.8*(4/9) = 52.8 lakhs

The total female population of below poverty line in state C

= > 118.8*(5/9) = 66 lakhs

Total male population in state C = 224.64 + 52.8 = 277.44 lakhs

Total female population in state C = 196.56 + 66 = 262.56 lakhs

Required difference = 277.44 – 262.56 = 14.88 lakhs

8) Answer: d)

The total population of below poverty line in state B = 117.6 lakhs

28 % of total population in state B = 117.6

Total population in state B = 117.6*(100/28) = 420 lakhs

The total population of above poverty line in state D = 550.8 lakhs

81 % of total population in state D = 550.8

Total population in state D = 550.8*(100/81) = 680 lakhs

Required total = 420 + 680 = 1100 lakhs

9) Answer: b)

The total population in state D = 680 lakhs

The female population of above poverty line in state D = The above poverty line population in state E

The female population of above poverty line in state D

= > 680*(81/100)*(5/9) = 306 lakhs

The above poverty line population in state E = 306 lakhs

68 % of total population in state E= 306

Total below poverty line population in state E

= > 306*(100/68)*(32/100) = 144 lakhs

Required difference = 306 – 144 = 162 lakhs

10) Answer: c)

The total population of above poverty line in state B = 302.4 lakhs

The total female population of above poverty line in state B

= > 302.4*(9/16) = 170.1 lakhs

The total population of below poverty line in state E = 144 lakhs

32 % of total population in state E = 144 lakhs

Total above poverty line population in state E

= > 144*(100/32)*(68/100) = 306 lakhs

Total female population of above poverty line in state E

= > 306*(4/9) = 136 lakhs

The average female population of above poverty line in state B and E together

= > (170.1 + 136)/2 = 153.05 lakhs = 15305000
