y^{2} -14y-4y +56 =0

(y – 14) (y – 4) =0

Y = 14, 4

Can’t be determined

**2) Answer: e)**

I. 5x^{2} -22x -15 =0

5x^{2} – 25x + 3x -15 =0

5x(x-5) – 3(x-5) =0

(5x-3) (x-5) =0

X= 3/5, 5

II. 7y^{2} -6y -81 =0

7y^{2} +21y – 27y -81 =0

7y(y+3)- 27(y+3) =0

Y = 27/7, -3

Can’t be determined

**3) Answer: e)**

I. 35x^{2} -3x -2 =0

35x^{2} +7x-10x -2 =0

7x (5x+1) – 2(5x+1) =0

I. x^{2} – 8x – 65 = 0

x^{2} + 5x – 13x – 65 = 0

x(x + 5) – 13(x + 5) = 0

(x – 13) (x + 5) = 0

X = 13, – 5

II. y = √841

Y = 29

X<y

**5) Answer: c)**

I. 3x^{2}+ 21x + 30 = 0

3x^{2}+ 6x + 15x + 30 = 0

3x (x +2) + 15(x + 2) = 0

6y^{2} + 3y + 10y + 5 = 0

3y (2y + 1) + 5(2y + 1) = 0

(3y + 5) (2y + 1) = 0

Y = -5/3, -1/2 = -1.67, – 0.5

X<y

**Direction (6-10)**

**6) Answer: c)**

2156 ÷ [(11/17) × (35/21) × (2/9)] = x

X = 2156 ÷ (2/9)

X = 2156*(9/2)

X = 9702 = 9700

**7) Answer: a)**

(3/7) * (35/13) * 3055 – x + (56/100)*7550 = 63

3525 – x + 4228 = 63

X = 3525 + 4228 – 63

X = 7690

**8) Answer: d)**

5*4350 + 6*3860 = x + 640

21750 + 23160 – 640 = x

X = 44270

**9) Answer: b)**

17 % of 17200 + 31 % of 2170 + 46 % of 19680 = x

X = (17/100)*17200 + (31/100)*2170 + (46/100)*19680

X = 2924 + 673 + 9053

X = 12650

**10) Answer: e)**

(48/100)*5250 + (96*96*3)/8 + 125 = 5x

5x = 2520 + 3456 + 125

5x = 6101

X = 1220

**11) Answer: c)**

Let the number of days required be x

According to the question,

27*40*6= 36*5*x

x= (27*40*6)/(36*5)

x= 36 days

**12) Answer: d)**

We know that, the difference between CI and SI for two years is

Difference = P*(r/100)^{2}

=> 1680 = P*(20/100)^{2}

=> 1680 = P*(1/5)^{2}

= > 1680 = P*(1/25)

=> P = Rs. 42000

SI = (42000 x 14 x 8)/100 = Rs. 47040

**13) Answer: a)**

P(E) = n(E)/n(S)

n(S) = ^{13}C_{2}

n(E) = ^{4}C_{2} or ^{6}C_{2}

P(E) = ^{4}C_{2} or ^{6}C_{2} / ^{13}C_{2}

P(E) = (6+15)/78

P(E) = 21/78 = 7/26

**14) Answer: c)**

Incomes and Rajiv and Mohan are in the ratio = 5 : 6 (5x, 6x)

According to the question,

(5x – 1000)/(6x – 2000) = 235/278

=> 1390x – 278000 = 1410x – 470000

=> 192000 = 20x

=> x = 9600

Income of Rajiv = 5x = 5 * 9600 = Rs. 48000

**15) Answer: a)**

(x – 4)/ 15 + (x-5)/18 + x/20 =1

(12x – 48+10x-50+ 9x)/180 =1

31x-98=180

31x= 278

X = 278/31 = 8 30/31 min

**Direction (16-20)**

**16) Answer: b)**

Total number of employees from Microsoft in 2015,

520*150/100 = 780

Senior employees in Microsoft = 780*70/100 = 546

**17) Answer: a)**

The no of senior employees from IBM in 2016 is 490,

70% of total employees = 490

Total employees = 700

The ratio of senior employees and other employees in the same year in IBM,

= > 490: 210

= > 7: 3

**18) Answer: a)**

718*x% + 530*40% + 564*25% = 712

718*x/100 + 212 +141 = 712

718*x/100 = 359

X = 359*100/718 = 50%

**19) Answer: c)**

Average = [520*55% + 700*70% + 1020*25% + 530*40% + 610*50%]/5

= (286 + 490 + 255+ 212 + 305)/5

= 1548/5

= 309

**20) Answer: e)**

The number of senior employees in 2016 = 680 + 255 + 490 = 1425

The number of senior employees in 2018 = 660 + 305 + 270 = 1235

Required difference = 1425 – 1235 =190
