II. 6y^{2} +37 y +35 =0

6y^{2} +30y+7y +35 =0

6y(y+5) + 7(y+5) =0

(6y+7) (y+5) =0

Can’t be determined

**2) Answer: a)**

I. 2x^{2} -11x +12 =0

2x^{2} -8x-3x +12 =0

2x(x-4)-3 (x-4) =0

(2x-3) (x-4) =0

X= 3/2, 4

II. 9y^{2} +21y +10 =0

9y^{2} +6y+15y +10 =0

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

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

Y= -5/3, -2/3

X>y

**3) Answer: e)**

I. X^{2} – 14x + 48 =0

(x – 8) (x – 6) =0

X= 8, 6

II. Y^{2} – 27y +72 =0

(y – 3) (y – 24) =0

Y= 3, 24

Can’t be determined

**4) Answer: b)**

(x-7) (x-5) =0

X= 7, 5

II. y^{2 }– 8y +15 =0

(y-5) (y-3) =0

Y= 5, 3

x ≥ y

**5) Answer: e)**

I. x^{2} +29x +54 =0

(x+27) (x+2) =0

X= -27, -2

II. y^{2 }+ 13y + 40 =0

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

Y= -8, -5

Can’t be determined

**Direction (6-10)**

**6) Answer: d)**

(48/100)*4250 + (x/100)*5600 = (52/100)*4650 + 1302

2040 + 56x = 2418 + 1302

56x = 2418 + 1302 – 2040

56x = 1680

X = 30

**7) Answer: a)**

(35/100)*x – (2652/17) – (2023/7) = 52

(7x/20) – 156 – 289 = 52

(7x/20) = 52 + 156 + 289

(7x/20) = 497

X = 497*(20/7) = 1420

**8) Answer: b)**

(50*23)/46 – (750/150) = 4x

25 – 5 = 4x

20 = 4x

X = 20/4 = 5

**9) Answer: e)**

27 % of 4500 – 32 % of 250 = x – √289 % of 1200

(27/100)*4500 – (32/100)*250 = x – (17/100)*1200

1215 – 80 = x – 204

1215 – 80 + 204 = x

X = 1339 = 1340

**10) Answer: c)**

74 % of 350 + 46 % of 1550 = x – (13)^{3}

(74/100)*350 + (46/100)*1550 = x – 2197

259 + 713 = x – 2197

X = 259 + 713 + 2197

X = 3169 = 3170

**11) Answer: b)**

Let the total profit be x,

A’s profit = (15/100)*x + (70/100)*x*(12/21)

2090 = (15/100)*x + (40/100)*x

(55/100)*x = 2090

X = 2090*(20/11) = Rs. 3800

B’s profit = 3800 – 2090 = Rs. 1710

**12) Answer: a)**

Perimeter of the field = 4500/7.50 = 600 m

2*(7x + 5x) = 600 => x = 25

So, length = 175 m & breadth = 125 m

Difference between length & breadth = (175 – 125) m = 50 m

**13) Answer: d)**

According to the question,

(12/15) + (x/25) = 1

(x/25) = 1 – (4/5)

(x/25) = (1/5)

X = (1/5)*25 = 5 min

**14) Answer: b)**

Compounded yearly,

= > 40000*(105/100)*(105/100) = 44100

C.I = 44100 – 40000 = 4100

Compounded half yearly,

=> 40000*(205/200)*(205/200)*(205/200)*(205/200) = 44152.515625

C.I = 44152.515625 – 40000 = 4152.515625 = 4153

Required difference = 4153 – 4100 = Rs. 53

**15) Answer: a)**

5 years hence, Akila: Preethi = 9: 10 (9x, 10x)

5 years ago, the age of Akila is equal to the age of Preethi, 10 years ago

= > (9x – 10) = (10x – 15)

= > x = 5

The present age of Akila = 9x – 5 = 40 years

**Direction (16-20)**

**16) Answer: c)**

The total production of Rice in all the given states together

= > (760 + 660 + 680 + 520 + 550)

= > 3170 thousand tonnes

The average production of Rice in all the given states together

= > (3170/5)

= > 634 thousand tonnes

**17) Answer: c)**

The total production of Pulses in Odisha, Bihar and Punjab together

= > 740 + 700 + 420

= > 1860 thousand tonnes

The total production of Wheat in Haryana, Bihar and West Bengal together

= > 580 + 640 + 460

= > 1680 thousand tonnes

Required ratio = 1860: 1680 = 186: 168 = 31: 28

**18) Answer: b)**

The total production of Jowar in all the given states together

= > 540 + 450 + 390 + 620 + 340

= > 2340 thousand tonnes

The total production of Bajra in all the given states together

= > 470 + 420 + 340 + 500 + 380

= > 2110 thousand tonnes

Required difference = 2340 – 2110 = 230 thousand tonnes

**19) Answer: a)**

Total production of Rice, Wheat and Jowar in Haryana and Bihar together

= > 660 + 580 + 450 + 680 + 640 + 390

= > 3400 thousand tonnes

Total production of Pulse, Wheat and Bajra in Odisha and West Bengal together

= > 740 + 770 + 470 + 530 + 460 + 500

= > 3470 thousand tonnes

Required % = (3400/3470)*100 = 97.98 % = 100 %

**20) Answer: b)**

The total production of Haryana and Bihar in all the given food grains together

= > 650 + 660 + 580 + 450 + 420 + 700 + 680 + 640 + 390 + 340

= > 5510 thousand tonnes

The total production of West Bengal and Punjab in all the given food grains together

= > 530 + 520 + 460 + 620 + 500 + 420 + 550 + 730 + 340 + 380

= > 5050 thousand tonnes

Required difference = 5510 – 5050 = 460 thousand tonnes
