Directions (Q. 31 – 35): In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and give answer

a) if x < y

b) if x > y

c) if x ≤ y

d) if x ≥ y

e) if x = y, or relationship between x and y can’t be established.

31. I. 7x + 3y = 8

II. 3x + 2y = 12

1. I. x2= 289

II. y = 3√2197

1. I. 8x2– 11x + 3 = 0

II. y2– 8y + 7 = 0

II. 2y2– 15y + 27 = 0

1. I. 10x2 – x – 24 = 0;

II. y2 – 2y = 0

8(1 / 2) + 4(2 / 7) = 5(1 / 2) + ?

Or, ? = 8(1 / 2) + 4(2 / 7) – 5(1 / 2)

= (8 + 4 – 5) + (1 / 2) + (2 / 7) – (1 / 2)

= 7 + [(7 + 4 – 7) / 14] = 7 + (4 / 14) = 7(2 / 7)

? = 376 – 58.4 × 1.5 × 2.2

= 376 – 192.72 = 183.28

(? × 4680) / 100 = 1183.4 – [(46 × 1250) / 100]

= 1183.4 – 575 = 608.4

? = (608.4 × 100) / 4680 = 13

√? + 9.5 = √2916 – √1681

= 54 – 41 = 13

√? = 13 – 9.5 = 3.5

? = 3.5 × 3.5 = 12.25

? = 4642 + 2368 + 196 – 5986

= 7206 – 5986 = 1220

Direction (6-10)

? = 2 * 36 – 5 = 67 ≈ 70

√? = 1394 / 100 – 7

√? = 14 – 7 = 7

? = 49

3* 12 = ? / 0.8

? = 36*0.8 = 36*(4/5)

? = 28.8 ≈ 30

? = 36 ÷ 9 ÷ 10 + 39

? = 4 / 10 + 39 = 39.4

? = 40

(?)2 = 59322 * (428 ÷ 11)

(?)2 = 39 * 39

? = 39

Direction (11-15)

224-16=208

Direction (16-20)

Total number of employees working in all the companies in 2010

= 2000 + 1750 + 2200 + 1800 + 1950 + 1500

= 11200

Total number of employees working in all the companies in 2014

= 1060 + 2000 + 1850 + 1650 + 1450 + 1500

= 9510

Required percentage = 11200/9510 x 100 = 120 %

Total number of employees working in C and D together in 2011 = 2400 + 1750 = 4150

Total number of employees working in A and B together in 2013 = 1400 + 1650 = 3050

Required percentage = (4150 – 3050)/3050 x 100 = 36.06%

Total number of employees working in 2011 = 1600 + 2050 + 2400 + 1750 + 1450 + 1700 = 10950

Total number of employees working in 2012 = 1350 + 1500 + 1200 + 1780 + 1300+ 2050 = 9180

Required ratio = 10950:9180 = 365 : 306

Total number of employees working in company B in all the years together

= 1750 + 2050 + 1500 + 1650 + 2000 = 8950

Total number of employees working in company D in all the years together

= 1800 + 1750 + 1780 + 1000 + 1650 = 7980

Required difference = 8950 – 7980 = 970

Required sum

= > 1950 + 1450 + 1300 + 1850 + 1450 + 1500 + 1700 + 2050 + 1450 + 1500

= > 16200

Selling price = 440*70/100 = Rs. 308

Cost price = 308/110*100 = Rs. 280

By using M1D1H1=M2D2H2

64*50/1/2= 20(50+x)/1/2

By solving

X= 110 men.

Total Balls = 15

Probability = 6C3 / 15C3 = 4/91

Distance covered by the first train= 18*40=720m

Distance covered by second train = 720-90=630m

So,

Time taken by the second train to cross the bridge= 630/84*5/18= 27 seconds.

Total capacity of the tank= 504 units

So, waste pipes empties the tank = 25/504-18/28-21/24=14/504 = 14 litres per minutes

So, waste pipe can empty 60% of the tank = 75/100*36=27 minutes

Let the distance of one side be x km

x/55 – x/66=1/2

x/330 = 1/2

x = 165 km

Volume of the sphere = 4/3πr3 = 4/3 x 22/7 x 14 x 14 x 14

Volume of the cylinder = πr2h = 22/7 x 14 x 14 x 16

Required ratio = [4/3 x 22/7 x 14 x 14 x 14] : [22/7 x 14 x 14 x 16]

= > 7:6

According to the question,

44000 x 115/100 x 120/100 x 90/100 = 54648

Required difference = 54648 – 44000 = 10648

Let the time of downstream and upstream x.

Speed of downstream= 6/x km/hr

Speed of upstream= 4/x km/hr

48/(6/x) + 48/(4/x) = 16

=>20x=16

=> x= 4/5 =0.8

Speed of downstream= 6/x = 6/0.8 = 7.5 km/hr

Speed of upstream= 4/x = 4/0.8 = 5 km/hr

The speed of the stream is,

=> ½ (7.5- 5)

=> 2.5/2 =1.25 km/hr

Consider M & N pipes opened together for x min

M——24min         total work

N—— 32min             96 units

Efficiency of M is 4

Efficiency of N is 3

7x+4(18-x) = 96

X = 8 minutes

1. 7x + 3y = 8
2. 3x + 2y = 12

Now, solving both the eqns, we get

eqn (i) x 2 – eqn (ii) x 3

(14x+ 6y=16) – (9x + 6y = 36)

5x = -20

x = -4 and y = 12

Hence, x <y

I. x2= 289

or x = ±17

II. y3√2197

y = 13

Hence, we can’t find a relationship between x and y.

I. 8x2 -11x + 3 = 0

8x2 – 8x – 3x +3 = 0

8x(x – 1) – 3(x – 1) = 0

(8x -3)(x – 1) = 0

x =1, 3/8

II. y2– 8y + 7 = 0

y2 – y – 7y + 7 = 0

y (y – 1) – 7(y – 1) = 0

(y – 1) (y – 7) = 0

y = 1, 7

Hence, x ≤ y

I. x2– 2x – 3x + 6 =0

x(x -2) – 3(x -2) = 0

(x -2) (x -3) = 0

x =2, 3

II. 2y– 6y – 9y + 27 = 0

2y(y – 3)-9(y -3) = 0

(y- 3) (2y -9) = 0

y = 3, 9/2

Hence, x ≤ y

I. 10x2 -16x + 15x – 24 = 0

2x(5x -8) + 3(5x 8)=0

(2x + 3)(5x +8) = 0

x = -3/2, 8/5

II. y2– 2y = 0

or, y(y -2) = 0

y = 0, 2

ie no relationship exists between x and y.
