1) Answer: c)

No of students in section III from school C = x

Total number of students in school C = x + 8 + 12 = 20 + x

Number of possible ways = 8C1 * 12C1 * xC1 * (20 + x тАУ 3) C1 = 25920

8 * 12 * x * (17+x) = 25920

17x + x2 = 270

= > x2 + 17x тАУ 270 = 0

= > x2 тАУ 10x + 27x тАУ 270 = 0

= > x (x тАУ 10) + 27 (x тАУ 10) = 0

= > x = 10, тАУ 27 (Eliminate the тАУVe value)

Number of students in section III from school C = 10

2) Answer: d)

Number of students in section III from school E = y

Total number of students in school E = (y + 12 + 18)

= y + 30

Number of possible ways = yC1 * 30C1 + yC2 = 195

= > y * 30 + (y*(y-1)/(1 *2)) = 195

= > 30y + (y2 тАУ y)/2 = 195

= > 60y + y2 тАУ y = 390

= > y2 + 59y тАУ 390 = 0

= > y2 + 65y тАУ 6y тАУ 390 = 0

= > y (y + 65) тАУ 6 (y + 65) = 0

= > (y + 65) (y тАУ 6) = 0

= > y = 6, -65 (Eliminate тАУVe value)

Total number of students in school E = 30 + 6 = 36

Required number of ways = 12C2 * 18C1 * 6C2

= (12*11 / 1*2) *18 *(6*5 / 1*2)

= 6*11*18*3*5

= 17820

3) Answer: b)

From I,

Number of students in section II from school A = n

Number of handshakes = nC2 = 105

= > [n*(n -1)] / (1 * 2) = 105

= > n2 тАУ n = 210

= > n2 тАУ n тАУ 210 = 0

= > n2 тАУ 15n + 14n тАУ 210 = 0

= > (n тАУ 15) (n тАУ 14) = 0

= > n = 15, -14 (Eliminate тАУVe value)

From statement I, We have to find only number of students in section II from school A. We canтАЩt find the total number of students.

Hence, statement I alone is not sufficient to answer the given question.

From II,

Total number of students in school A = x

Number of handshakes = xC2 = 780

= > x * (x тАУ 1)/1*2 = 780

= > x2 тАУ x = 780*2

= > x2 тАУ x тАУ 1560 = 0

= > x2 тАУ 40x + 39x тАУ 1560 = 0

= > x (x тАУ 40) + 39 (x тАУ 40) = 0

= > (x тАУ 40) (x + 39) = 0

= > x = 40, -39 (Eliminate тАУVe value)

Total number of students in school A is 40.

Hence, Statement II alone is sufficient to answer the given question.

4) Answer: a)

Number of students in section II from school B = x

Number of students in section III from school B = 75/100 * x

= 3x/4

Total number of students in section II and III from school B = 20 тАУ 6 = 14

= > x + 3x/4 = 14

= > 7x/4 = 14

= > x = 8

Number of students in section III from school B = 8 * 75/100 = 6

Quantity I:

Number of ways = 6C1*8C1*6C1*(20-3)C2

= 6 * 8 * 6 *(17*16/1*2)

= 6*8*6*17*8

= 39168

Quantity II: In committee Q, five students is to be formed from school B such that committee contains at least one student from section I.

Number of ways = 6C1*14C4 + 6C2*14C3 + 6C3*14C2 + 6C4*14C1 + 6C5

= 6006 + 5460 + 1820 + 210 + 6

= 13502

Hence, Quantity I > Quantity II

5) Answer: d)

Number of ways in school D = 8C3

= 8*7*6 / 1*2*3 = 56

Number of ways in school B = 6C3

= 6*5*4 / 1*2*3 = 20

Required percentage = (56/20) * 100 = 280%

6) Answer: b)

Required percentage = (1750/500) x 100 = 350%

7) Answer: a)

Required sum = 1250 + 1750 + 2000 + 750 + 2500 + 1000 = 9250

8) Answer: c)

Number of items sold by all the companies in 2010 = 1750 + 2000 + 1500 + 1250 + 750 = 7250

Number of items sold by company C in all the years together = 1500 + 500 + 2250 = 4250

Required percentage = (7250 тАУ 4250)/4250 x 100 = 70.58%

9) Answer: a)

Total number of items sold by all the companies in 2011 = 2250 + 3000 + 500 + 1750 + 2500 = 10000

Total number of items sold by all the companies in 2012 = 1250 + 1500 + 2250 + 2000 + 1000 = 8000

Required difference = 10000 тАУ 8000 = 2000

10) Answer: d)

Total number of items sold by companies B, E in 2010 = 2000 + 750 = 2750

Total number of items sold by companies A and D in 2012 = 1250 + 2000 = 3250

Required ratio = 2750 : 3250 = 11:13

1) Answer: c)

Total number of students enrolled for Dancing = 2500*(18/100) = 450

Total number of students enrolled for Singing = 2500*(14/100) = 350

Total number of girl students enrolled for Dancing =1200*(21/100) = 252

Total number of girl students enrolled for Singing = 1200*(12/100) = 144

Total number of boy students enrolled for Dancing = 450 тАУ 252 = 198

Total number of boy students enrolled for Singing = 350 тАУ 144 = 206

Required % = [(198 + 206)/(252 + 144)]*100

= > (404/396)*100 = 102.02 % = 102 %

2) Answer: b)

The total number of students enrolled for Drawing and Karathe together

= > 2500*(52/100) = 1300

The total number of girl students enrolled for Karathe and Swimming together

= > 1200*(50/100) = 600

Required difference = 1300 тАУ 600 = 700

3) Answer: d)

Total number of students enrolled for Dancing = 2500*(18/100) = 450

Total number of girl students enrolled for Dancing =1200*(21/100) = 252

Total number of boy students enrolled for Dancing = 450 тАУ 252 = 198

Total number of students enrolled for Swimming = 2500*(16/100) = 400

Total number of girl students enrolled for Swimming = 1200*(23/100) = 276

Total number of boy students enrolled for Swimming = 400 тАУ 276 = 124

The total number of boy students enrolled for Dancing and Swimming together

= > 198 + 124 = 322

The total number of girl students enrolled for Drawing and Karathe together

= > 1200*(44/100) = 528

Required ratio = 322 : 528 = 161 : 264

4) Answer: a)

Total number of students enrolled for Singing = 2500*(14/100) = 350

Total number of girl students enrolled for Singing= 1200*(12/100) = 144

Total number of boy students enrolled for Singing = 350 тАУ 144 = 206

Total number of students enrolled for Drawing = 2500*(24/100) = 600

Total number of girl students enrolled for Drawing = 1200*(17/100) = 204

Total number of boy students enrolled for Drawing = 600 тАУ 204 = 396

Total number of students enrolled for Karathe = 2500*(28/100) = 700

Total number of girl students enrolled for Karathe = 1200*(27/100) = 324

Total number of boy students enrolled for Karathe = 700 тАУ 324 = 376

Total number of boy students enrolled for Singing, Drawing and Karathe together

= > 206 + 396 + 376 = 978

Required average = 978/3 = 326

5) Answer: c)

Total number of students enrolled for Singing and Swimming together

= > 2500*(30/100) = 750

Total number of girl students enrolled for Dancing, Drawing and Karathe together

= > 1200*(65/100) = 780

Required % = [(780 тАУ 750)/780]*100 = (30/780)*100 = 4 % less
