**Directions (Q. 16 – 20) In the following questions, two equations I and II are given. You have to solve both the equations and g****ive answer as,**

- If x > y
- If x ≥ y
- If x < y
- If x ≤ y
- If x = y or the relation cannot be established

**I.**3/√x + 7/√x = √x

II.y^{2} = 12^{5/2}/ √y

**I.**x^{3}= 2744

II.y^{2} – 11y – 60 = 0

**I.**3x = 5y – 4

II. 5x + 7y – 70 = 0

**I.**x^{2}+ 12x + 32 = 0

II. 3y^{2} – 10y + 7 = 0

20. ** I. **x^{2} = 14161

II. y = √14161

**Answers:**

**1. Answer e**

From (I),

Father – son = 24

From (II),

Present age of son = (1/5)*present age of father

Present age of son/present age of father = (1/5)

The ratio of present age of son and father = 1 : 5(x, 5x)

Father – son = 24

5x – x = 24

4x = 24

X = 6

The present age of father = 5x = 30 years

Both (I) and (II) follows.

**2. Answer e**

From (I) and (II),

Let the length of the train be x,

Speed = Distance / Time

Distance = Train length + Bridge length = x + 240

Speed of the train = 54 km/hr

54*(5/18) = (x + 240)/28

54*(5/18)*28 = x + 240

420 = x + 240

X= 420 – 240 = 180 m

Length of the train = 180 m

**3. Answer a**

From I,

Perimeter of rectangle = 300 m

2(l + b) = 150

l + b = 75

l + 30 = 75

l = 45 m

Area of rectangle = lb = 30*45 = 1350 Sq m

From II,

We can’t find the area of rectangle.

**4. Answer a**

From I,

Let the cost price be Rs. 100

If no discount is given 20 % profit is gained.

MP = 100*(120/100) = Rs. 120

SP = 120*(95/100) = Rs. 114

P % = (Profit/CP)*100

= > (14/100)*100 = 14 %

From II,

The cost price of the article only given, So, we can’t find the profit %.

**5. Answer e**

From both the statements,

From I,

Let the principal be x,

Amount= 2x

Simple interest= 2x-x= x

Rate= 100*x/10*x= 10%

From II,

Sum of money invested by Rohit

= 2400*100/2*10

= Rs. 12000

**Directions (6-10):**

**Solution:**

Area of hall= 33*39= 1287m^{2}

Area of Chairman’s room=13*12=156m^{2}

Area of Principal room= 23*13= 299m^{2}

Area of office room= 14*12= 168 m^{2}

Area of Vice principal room= 12*23= 276 m^{2}

Thus total area to be floored= 2186 m^{2}

**6. Answer: e**

Area of wall=2(12*13+12*12)= 2(300)= 600 m^{2}

We know that Area of the Chairman’s room= 156 m^{2}

Now cost of paining of four walls=145*(600+156)= Rs 109620

And cost of flooring= 210*156=Rs 32760

Hence total cost= 109620+32760=Rs 142380

**7. Answer: b**

Total flooring area with wood= 1287+156= 1443 square meter

Cost of flooring area with wood= 1443*210= Rs 303030

Now total flooring area with marble= 743*240=Rs 178320

Hence required ratio= 303030 – 178320= Rs 124710

**8. Answer: a**

Total cost of renovation of the hall= 1287*210=Rs 270270

The cost of renovating the Vice principal’s room= 276*240= Rs 66240

Now required total cost= 270270+ 66240= Rs 336510

9. **Answer: d**

Given that, total area of the college= 2500 square meter

Now, remaining area= 2500-2186= 314 square meter

Thus cost of renovation of the remaining area= 314* 280=Rs 87920

**10. Answer: c**

Total area of the college that is not to be renovated= 2500-2186=314 square meter

Thus required percentage= 314/2500*100= 13%

**11. Answer d**

The share of A, B and C

= > [(50000*6) + (55000*6)]: [35000*12]: [55000*6 + 45000*6]

= > 630000: 420000: 600000

= > 21: 14: 20

Total profit = Rs. 26785

55’s = 26875

1’s = (26875/55) = 487

The share of B = 14’s = Rs. 6818

**12. Answer a**

1 man’s 1 day’s work= 1/90

1 woman’s 1 day’s work= 1/144

1 child’s 1day’s work= 1/180

So,

Required days = (10/90 +6/144 +15/180)

= 1/9 + 1/24 + 1/12

= 17/72

Required days = 72/17 = 4 4/17 days

**13. Answer c**

4 years ago, the ratio of age of A and B = 3 : 5 (3x, 5x)

After 12 years, the sum of the ages of A and B = 64

= > 3x+ 16 + 5x + 16 = 72

= > 8x + 32 = 72

= > 8x = 40

= > x = 5

The present age of A and B = 3x + 4, 5x + 4 = 19, 29

C = D + 8

C – D = 8 —> (1)

The average of present ages of A, B, C and D = 25 years

The total present ages of A, B, C and D = 25*4 = 100

= > 19 + 29 + C + D = 100

= > C + D = 100 – 48

= > C + D = 52 –> (2)

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

C = 30, D = 22

The present age of C and D = 30 years and 22 years

**14. Answer b**

Total probability n(S) = 18C_{2}

Required probability n(E) = 4C_{2} or 6C_{2} or 8C_{2}

P(E) = n(E)/n(S) = (4C_{2} or 6C_{2} or 8C_{2})/ 18C_{2}

= > (6+15+28)/153

= > 49/153

**15). Answer a**

The perimeter of a rectangle = 80 m

2(l + b) = 80

l + b = 40 –> (1)

l – b = 8 –> (2)

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

L = 24 m, b = 16 m

The area of rectangle + 16 = The Area of square

The area of rectangle = lb = 24*16 = 384 Sq m

The area of square = 384 + 16 = 400 Sq m

(a^{2}) = 400

Side (a) = 20 m

The perimeter of square = 4*20 = 80 m

**Direction (16-20)**

**16. Answer c**

I. 3/√x + 7/√x = √x

(3 + 7)/ √x = √x

X = 10

II. y^{2} = 12^{5/2}/ √y

**y ^{2} × **√y = 12

^{5/2}

y^{2} ^{+ (1/2)} = 12^{5/2}

y^{5/2} = 12^{5/2}

y = 12

**x < y**

**17. Answer e**

I. x^{3} = 2744

X = 14

II. y^{2} – 11y – 60 = 0

(y – 15)(y + 4) = 0

Y = 15, -4

**Can’t be determined**

**18. Answer a**

3x – 5y = 4–> (1)

5x + 7y = 70–>(2)

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

X = 7, y = 5

**x > y**

**19. Answer c**

I. x^{2}+ 12x + 32 = 0

x^{2}+ 8x + 4x + 32 = 0

x(x+ 8)+4 (x +8) = 0

(x+ 4)(x+8) = 0

X = -4, -8

II. 3y^{2} – 10y + 7 = 0

3y^{2} – 3y – 7y + 7 = 0

3y(y – 1) – 7(y – 1) = 0

(3y – 7)(y – 1) = 0

Y = 7/3, 1 = 2.33, 1

**x < y**

**20. Answer d**

I. x^{2} = 14161

X = +119, -119

II. y = √14161

Y = 119

**x ****≤ ****y**
