The answer is, 3105

**5) Answer: a)**

The pattern is, *3 + 1, *6 + 2, *9 +3, *12 + 4, *15 + 5,..

The answer is, 130205

**Direction (6-10)**

**6) Answer: c)**

(35/100)*620 + (3/11)*20350 – (17/100)*800 = x

X = 217 + 5550 – 136

X = 5631

**7) Answer: d)**

(x/100)*600 = 2562 + [(67 + 34) (67 – 34)] *(42/11)

6x = 2562 + (101*33)*(42/11)

6x = 2562 + 12726

6x = 15288

X = 2548

**8) Answer: b)**

6716/23 + 49^{2} + (2/9)*3564 – 52 = x

X = 292 + 2401 + 792 – 52

X = 3433

**9) Answer: a)**

6 3/8 + 5 ¾ – 4 ½ – 3 1/8 + 7 ½ = x

X = (6 + 5 – 4 – 3 + 7) (3/8 + ¾ – ½ – 1/4 + ½)

X = 11 [(3 + 6 – 2)/8

X = 11 (7/8)

**10) Answer: d)**

(36/100)*3450 + (3/7)*3164 – (135*123)/5535 = x

X = 1242 + 1356 – 3

X = 2595

**11) Answer: a)**

Let the side of a cube be a,

Volume of a cube = a^{3}

Side of the new cube = a*(130/100) = 1.3 a

Volume of new cube = (1.3 a)^{3} = 2.197 a^{3}

Increase % = [(1.197 a^{3})/a^{3}]*100 = 119.7 %

**12) Answer: d)**

The ratio of age of A, 5 years ago and the age of B, after 3 years

= > 3 : 4 (3x, 4x)

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

Sum of the ages of A and B together, after 5 years = 47 years

3x + 5 + 4x – 3 + 10 = 47

7x + 12 = 47

7x = 47 – 12 = 35

X = 5

The average of present age of A, B and C = 20 years

Total present age of A, B and C = 60 years

The present age of C = 60 – [20 + 17] = 23 years

**13) Answer: b)**

Total capacity of the tank = 1500 litres

P = 1500/125 = 12 litres per hour

Q = 1500/100 = 15 litres per hour

Required % = [(15 – 12)/12]*100 = 25 %

**14) Answer: d)**

C.I = P*[(1 + (r/200))^{2n} – 1]

1827 = P*[(1 + (6/200))^{2} – 1]

1827 = P*[(103/100)^{2} – 1]

1827 = P*[(10609/10000) – 1]

1827 = P*[609/10000]

P = 1827*(10000/609) = Rs. 30000

**15) Answer: b)**

The ratio of investment of A, B and C = 4: 3: 6

The ratio of shares of A, B and C = 16: 15: 12

Investment ratio*Period ratio = Ratio of Profit

Period ratio = Ratio of Profit/Investment ratio

According to the question,

= > (16/4) : (15/3) : (12/6)

= > 4 : 5 : 2

**Direction (16-20)**

**16) Answer: c)**

Total number of students appeared for final examination from School A in the year 2011 and 2015 together

= > 1250 + 1400 = 2650

Total number of students appeared for final examination from School B in the year 2012 and 2014 together

= > 1150 + 1350 = 2500

Required % = (2650/2500)*100 = 106 %

**17) Answer: a)**

The total number of students appeared for final examination from School A in all the given years

= > 1250 + 950 + 750 + 1500 + 1400 + 1150 = 7000

The total number of students appeared for final examination from School B in all the given years

= > 1000 + 1150 + 900 + 1350 + 1500 + 1200 = 7100

Required difference = 7100 – 7000 = 100

**18) Answer: d)**

The total number of students appeared for final examination from both the schools in 2016

= > 1150 + 1200 = 2350

The total number of students passed from both the schools in 2016

= > 1150*(82/100) + 1200*(91/100)

= > 943 + 1092 = 2035

Required ratio = 2350 : 2035 = 470 : 407

**19) Answer: b)**

The ratio of total number of male to that of female students appeared for final examination from School A in 2011 = 13: 12

The total number of female students appeared for final examination from School A in 2011

= > 1250*(12/25) = 600

The ratio of total number of male to that of female students appeared for final examination from School A in 2013 = 7 : 8

The total number of female students appeared for final examination from School A in 2013

= > 750*(8/15) = 400

The average number of female students appeared for final examination from School A in 2011 and 2013

= > (600 + 400)/2 = 1000/2 = 500

**20) Answer: a)**

The average number of students appeared from School A and B together in the year 2012, 2013 and 2014

= > (950 + 1150 + 750 + 900 + 1500 + 1350)/2

= > 6600/2

= > 3300
