** Answers:**

**Directions (Q. 1 – 5): **

**Answer: d**

55x = (3565 + 776) ÷ 35 + 56^{2} + (4/7) of 847 – 59

55x = (4341/35) + 3136 + (4/7)* 847 – 59

55x = 124 + 3136 + 484 – 59

55x = 3685

X = 67

**Answer: a**

(2/5) of (65/26) of 4145 = 27 % of 2800 + (3/7) of (?)

4145 = (27/100)*2800 + (3/7)*x

4145 = 756 + (3/7)*x

4145 – 756 = (3/7)*x

3389 = (3/7)*x

3390*(7/3) = x

X = 7908 = 7900

**Answer: c**

615 × 1754 ÷ [(27/100)*1300] = (45*270)/9 + x – 4900

615 × 1754 ÷ 351 = 1350 + x – 4900

(615*1755)/351 = 1350 + x – 4900

3075 + 4900 – 1350 = x

X = 6625

**Answer: b**

(14/39) ÷ (168/351) × 216 + 1249 – 69 % of 600 = x

X = (14/39)*(351/168)*216 + 1249 – (69/100)*600

X = 162 + 1249 – 414

X = 997 = 1000

**Answer: e**

(3564/12) ÷ 3 × 36 + 32% of 4500 – 37 % of 1300 = x

X = (3564/12) *(1/3)*36 + (32/100)*4500 – (37/100)*1300

X = 3564 + 1440 – 481

X = 4523 = 4500

**Directions (Q. 6 – 10) **

**Answer: a**

I. x^{2} – 17x + 72 = 0

(x – 9) (x – 8) = 0

X = 9, 8

II. 2y^{2} – 11y + 12 = 0

2y^{2} – 8x – 3y + 12 = 0

2y(y -4) – 3(y – 4) = 0

(2y – 3) (y – 4) = 0

Y = 3/2, 4 = 1.5, 4

X > y

**Answer: e**

I. x^{3/4} = 6 × x^{1/4}

X^{3/4 }÷ x^{1/4} = 6

X^{3/4 – ¼} = 6

X^{2/4} = 6

X^{1/2} = 6

X = 6^{2} = 36

II. √y + (1521)^{1/2} = √2025

√y = 45 – 39

√y = 6

Y = 6^{2} = 36

X = y

**Answer: a**

5x + 9y = 47 –> (1)

3x + 5y = 27 —> (2)

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

X = 4, y = 3

X > y

**Answer: e**

I. 5x^{2} – 12x – 65 = 0

5x^{2} – 25x + 13x – 65 = 0

5x(x – 5) + 13(x – 5) = 0

(5x + 13) (x – 5) = 0

X = -13/5, 5 = -2.6, 5

II. 7y^{2} + 7y – 42 = 0

7y^{2} -14y + 21y– 42 = 0

7y(y – 2) + 21 (y – 2) = 0

(7y + 21) (y – 2) = 0

Y = -21/7, 2 = -3, 2

Can’t be determined

**Answer: e**

I. 3x^{2} – 8x – 35 = 0

3x^{2} – 15x + 7x – 35 = 0

3x(x – 5) + 7(x – 5) = 0

(3x + 7) (x – 5) = 0

X = -7/3, 5 = -2.33, 5

II. 2y^{2} + 10y – 28 = 0

2y^{2} – 4y + 14y – 28 = 0

2y(y -2) + 14(y – 2) = 0

(2y + 14) (y – 2) = 0

Y = -14/2, 2 = -7, 2

Can’t be determined

**Answer: c**

The present age of Arun = (144/100)* the present age of Raghav

The ratio of present age of Arun and Raghav = 36: 25 (36x, 25x)

11x = 22

X = 2

Present age of Raghav = 25x = 50 years

**Answer: a**

Distance covered by the first train= 35*18= 630 m

Distance covered by the second train = 630-130 = 500 m

Time taken by the second train to cross the bridge

= > 500/(72*5/18)

= > (500*18)/(72*5)

= > 25 seconds

**Answer: d**

Amount = P(1 + r/100)^{n}

37044 = 32000(1 + (5/100))^{n}

(37044/32000) = (105/100)^{n}

(37044/32000) = (21/20)^{n}

(9261/8000) = (21/20)^{n}

(21/20)^{3} = (21/20)^{n}

n = 3 years

**Answer: b**

The ratio of milk to water in a solution = 3: 1 (3x, x)

According to the question,

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

21x = 6x + 90

15x = 90

X = 6

Initially, Milk = 3x = 18 litres

**Answer: a**

The share of A, B and C,

= > [25000*7 + 20000*5]: [18000*4 + 25000*8]: [32000*12]

= > 275000: 272000: 384000

= > 275: 272: 384

931’s = 97755

1’s = 105

The share of C = 385’s = Rs. 40425

**Directions (Q. 16 – 20) **

**Answer: d**

Total number of successful candidates of IAS examination from state S

= > 5000*(26/100) = 1300

Total number of candidates appeared for IAS examination from state P

= > 90000*(24/100) = 21600

Required % = (1300/21600)*100 = 6 %

**Answer: a**

The total number of candidates appeared for IAS examination from state Q and S together

= > [(21 + 16)/100]*90000 = 33300

The total number of successful candidates of IAS examination from state P, Q, R and T together

= > [(22 + 15 + 17 + 20)/100]*5000 = 3700

Required ratio = 33300: 3700 = 333: 37

**Answer: c**

The total number of unsuccessful candidates of State R

= > [90000*(19/100)] – [5000*(17/100)]

= > 17100 – 850 = 16250

The total number of unsuccessful candidates of State S

= > [90000*(16/100)] – [5000*(26/100)]

= > 14400 – 1300 = 13100

Required difference = 16250 – 13100 = 3150

**Answer: b**

The total number of unsuccessful candidates of State P, Q and R together

= > {[90000*(24/100)] – [5000*(22/100)]} + {[90000*(21/100)] – [5000*(15/100)]} + {[90000*(19/100)] – [5000*(17/100)]}

= > (21600 – 1100) + (18900 – 750) + (17100 – 850)

= > 20500 + 18150 + 16250

= > 54900

Required average = 54900/3 = 18300

**Answer: d**

Required % = [(45 – 36)/36]*100 = 25 %
