** Answers:**

**1). Answer: c**

The difference is, ÷ 3

The answer is, 3273

**2). Answer: a**

The pattern is, *0.5 – 1, *1 -1, *1.5 -1, *2 -1, *2.5 -1,..

The answer is, 111.5

**3). Answer: d**

The pattern is, *1 + 2, *2 – 2, *3 + 2, *4 – 2, *5 +2,..

The answer is, 4712

**4). Answer: b**

The pattern is, *2 – 3^{2}, *3 + 4^{2}, *4 – 5^{2}, *5 + 6^{2}, *6 – 7^{2},..

The answer is, 1697

**5). Answer: e**

The pattern is, *1/2, *3/2, *5/2, *7/2,..

The answer is, 236.25

**Direction (6-10)**

**6). Answer: a**

(3/5) * (12/17) * 14025 – x + (48/100)*650 = 58

5940 – x + 312 = 58

6194 = x

**7). Answer: d**

44 – (31/x) + (2/5)*375 – 48 = 22

44 – (31/x) + 150 – 48 = 22

44 + 150 – 48 – 22 = (31/x)

124 = (31/x)

X = 124/31 = 4

**8). Answer: b**

(53/800)*9600 + ((1425/25)/3) = 127 + x

636 + 19 – 127 = x

X = 528

**9). Answer: c**

2717 ÷ [(22/100) * 650] = 35 × 5 3/7 of (17 ÷ x)

2717 ÷ 143 = 35 * (38/7)*(17/x)

19 = 35 * (38/7)*(17/x)

X = 35*(38/7)*(17)*(1/19)

X = 170

**10). Answer: a**

(56/100)*4250 + (36/100)*750 + (23/100)*x = 2788

2380 + 270 + (23/100)*x = 2788

(23/100)*x = 2788 – 2380 – 270

(23/100)*x = 138

X = 138*(100/23)

X = 600

**11). Answer: d**

The successful candidate got 56% of the valid votes and won by a majority of 1728 votes.

(56 % – 44 %) of votes = 1728

12 % of votes = 1728

According to the question,

20 % voters didn’t cast their votes and 10 % of the votes are invalid. So,

= > (80/100)*(90/100)* total voters = 1728*(100/12)

= > Total voters = (1728*10*10*100) / (8*9*12) = 20000

**12). Answer: a**

Diff = Sum*(r/100)^{2}

160 = Sum*(8/100)^{2}

160*100*100/64 = Sum

Sum = Rs. 25000

**13). Answer: b**

6 years ago, the ratio of ages of A and B = 2: 3 (2x, 3x)

Present ages of A and B = 2x + 6, 3x + 6

After 6 years, the ratio of ages of A and B = 3: 4

According to the question,

(2x + 12)/(3x + 12) = (3/4)

8x + 48 = 9x + 36

X = 12

Sum of the present ages of A and B = 2x + 3x + 12 = 72 years

**14). Answer: d**

Let the speed of two trains be X and Y

Same direction,

54 = (150+150)/[(X – Y)*5/18]

54 = (300*18)/[(X – Y)*5]

X – Y = 20 —> (1)

Opposite direction

12 = (150+150)/[(X + Y)*5/18]

12 = (300*18)/[(X + Y)*5]

X + Y = 90 —> (2)

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

Y= 35 km/hr, X= 55km/hr

**15). Answer: c**

Speed of upstream = (48*60) / 72 = 40 km/hr

Speed of current: Speed of still water = 2: 7

Speed of upstream = Speed of still water – speed of Current

40 = 5x => x =8

Speed of current = 16 km/hr

Speed of still water = 56 km/hr

Speed of downstream= Speed of still water + speed of Current

= > 56 + 16 = 72 km/hr

Speed = 72 km/hr, Time = 90 minutes

Distance = 72*(90/60)** = **108 km

**Direction (16-20)**

**16). Answer: a**

Total number of male who are all visiting the places India Gate and Red Fort together

= > 23650*(5/11) + 24768*(4/9)

= > 10750 + 11008 = 21758

Total number of female who are all visiting the places Taj Mahal and Gateway of India together

= > 21915*(4/9) + 20170*(2/5)

= > 9740 + 8068 = 17808

Required % = (21758/17808)*100 = 122 % = 120 %

**17). Answer: c**

The total number of Andhra Pradesh people who are all visiting Golden Temple

= > 25800*(29/100) = 7482

**18). Answer: b**

The total number of females who are all visiting India Gate, Red Fort and Gateway of India together

= > 23650*(6/11) + 24768*(5/9) + 20170*(2/5)

= > 12900 + 13760 + 8068

= > 34728

Required average = 34728/3 = 11576

**19). Answer: d**

The total number of people who are all visiting Golden Temple and Red Fort together

= > 25800 + 24768 = 50568

The total number of males who are all visiting India Gate and Gateway of India

= > 23650*(5/11) + 20170*(3/5)

= > 10750 + 12102 = 22852

Required difference = 50568 – 22852 = 27716

**20). Answer: a**

** **The total number of males who are all visiting Red Fort

= > 24768*(4/9) = 11008

The total number of females who are all visiting Taj Mahal

= > 21915*(4/9) = 9740

Required ratio = 11008: 9740 = 2752: 2435
