Directions (1-5) :

I) 3x2 + 23x + 42 = 0

=> (3x + 14)(x + 3) = 0

=> x = -14/3, -3

II) y2 + 4y – 21 = 0

=> (y – 3)(y + 7) = 0

=> y = 3, -7

Hence, relationship between x and y cannot be determined.

I) 14x2 – 132x + 238 = 0

=> 2 x (7x2 – 66x + 119) = 0

=> 7x2 – 66x + 119 = 0

=> (x – 7)(7x – 17) = 0

=> x = 7, 17/7

II) 4y2 – 17y + 13 = 0

=> (y – 1)(4y – 13) = 0

=> y = 1, 13/4

Hence, relationship between x and y cannot be determined.

I) 5x2 – 19x + 12 = 0

=> (5x – 4)(x – 3) = 0

=> x = 4/5, 3

II) 3y2 + 14y + 15 = 0

=> (y + 3)(3y + 5) = 0

=> y = -3, -5/3

Hence, x > y

I) 4x2 + 3x – 10 = 0

=> (4x – 5)(x + 2) = 0

=> x = 5/4, -2

II) y2 – (343)1/3 – √841 = 0

=> y2 – 7 – 29 = 0

=> y2 = 36

=> y = ±6

Hence, relationship between x and y cannot be determined.

I) 6x2 – 25x + 24 = 0

=> (2x – 3) (3x – 8) = 0

=> x = 3/2, 8/3

II) 5y2 + 27y + 10 = 0

=> (y + 5) (5y + 2) = 0

=> y = -5,

-2/5                                                                                                                                                                                                                                                                  Hence, x > y

Directions (6-10) :

From I:

Aman, Sunil and Kabir entered into a partnership for three years and at the end of three years they earned a profit of Rs.200000.

From II:

Ratio of investment amount of Aman, Sunil and Kabir is 3:5:4 respectively:.

From III:

At the end of two years, Kabir doubled his investment.

From I, II and III:

Let the investment amounts of Aman, Sunil and Kabir be Rs.3x, Rs.5x and Rs.4x respectively.

Ratio of share in the profit:

Aman : Sunil : Kabir = (3x + 3x + 3x) : (5x + 5x + 5x) : (4x + 4x + 8x)

= 9x: 15x: 16x

= 9:15:16

Share of Aman in the profit = 9/40 x 200000 = Rs.45000

Hence, all I, II and III together are sufficient.

From I:

Speed(train) : Speed(bus) : Speed(car) = 8 : 2 : 3

From II:

Speed(car) = 216/8 = 27 km/h

From III:

Speed (bus) = 24/2 = 12 km/h

From I and II:

Speed (train) = 8/3 x 27 = 72 km/h

Required distance = 72 x 9 = 648 Km

From I and III:

Speed (train) = 8/2 x 12 = 48 km/h

Required distance = 48 x 9 = 432 km

Hence, only I and Either II or III are sufficient.

From I:

Probability of drawing one red ball from the bag is 1/3

From II:

Red = 4

Green = 3

Blue = x (let)

From III:

Blue < Red

From I and II:

4/(4 + 3 + x) = 1/3

=> 12 = 4 + 3 + x

=> x = 12 – 7

=> x = 5

Required probability = 5/(4 + 3 + 5) = 5/12

Hence, only I and II are sufficient.

From I and II:

Let the present ages of Mauli and Nandini be 5x years and 4x years respectively.

(5x – 5)/(4x – 5) = 4/3

=> 15x – 15 = 16x – 20

=> x = 5

Age of Mauli after ten years = 5x + 10 = 5 x 5 + 10 = 35 years

From I and III:

Let the present ages of Mauli and Nandini be 5x years and 4x years respectively.

(5x + 10)/(4x + 10) = 7/6

=> 30x + 60 = 28x + 70

=> 2x = 10

=> x = 5

Age of Mauli after ten years = 5x + 10 = 5 x 5 + 10 = 35 years

From II and III:

Let the ages of Mauli and Nandini before five years be 4x years and 3x years respectively

(4x + 15)/(3x + 15) = 7/6

=> 24x + 90 = 21x + 105

=> 3x = 15

=> x = 5

Age of Mauli after ten years = 4x + 15 = 4 x 5 + 15 = 35 years

Hence, any two of the three statements are sufficient.

From I:

Roshni + Sitara + Kumud + Mini = 4 x 26 + 4 x 4 = 120 years

From II:

Roshni + Sitara = 2 x 31 = 62 years

From III:

Mini = Kumud – 2

From I, II and III

Roshni + Sitara + Kumud + Mini = 4 x 26 + 4 x 4 = 120 years

Roshni + Sitara = 2 x 31 = 62 years

Mini = Kumud – 2

Roshni + Sitara + Kumud + Mini = 120

=> 62 + kumud + Kumud – 2 = 120

=> 60 + 2 x kumud = 120

=> 2 x Kumud = 120 – 60

=> Kumud = 60/2

=> Kumud = 30 years

Hence, all I, II and III together are sufficient.
