Answers:

1) Answer: a)

Total units of work= 60

Pipe A’s one hour work= 3 units

Pipe C’s one hour work= 5 units

Work done by pipe A in 4 hours to fill the rest of the tank= 3*4= 12 units

Remaining work was done by pipe A and C= 60-12= 48

Time for which pipe C was open = 48/8= 6 hours

2) Answer: a)

Total units of work= 150

Pipe D’s one hour work= 6 units

Pipe F’s one hour work= 10 units

Pipe B’s one hour work= 5 units

Time taken by pipes D and F to fill 64% of the tank= 96/ (10+6) = 6 hours

Remaining units= 54

Time taken to fill the tank= 54/ (6+10+5) = 54/21 hours

Total time taken to fill the cistern= 6+ 54/21= 8(4/7) hours

3) Answer: d)

Total units of work= 60

Pipe A’s one hour work= 3 units

Pipe B’s one hour work= 2 units

Pipe P’s one hour work= 4 units

Three pipes one hour work= 3+2-4= 1 units

So, time require to fill the empty tank= 60/1= 60 hours

4) Answer: d)

Liters of water filled by pipe C in 5(5/11) hours

= 1/12* 60/11=5/11

= 5/11* 3300= 1500 liters.

So pipe C can fill liters of water in one hour= 1500*11/60= 275 liters.

5) Answer: c)

Total units of work= 24

Work done pipe S in one hour= ½* 4= 2 units

Work done pipe T in one hour= 2/3* 3= 2 units

So, the time taken to empty the tank= 24 /4= 6 hours

Direction (6-10)

6) Answer: a)

The probability that all the three balls are of same color

= (4C3 + 6C3+ 3C3)/ 15C3

= (4+20+1)*6/15*14*13

= 25*6/15*14*13

= 5/91

7) Answer: a)

Probability of both the balls of white color

= 4C2/13C2

= 6/ 78

= 1/13

8) Answer: b)

The probability that at least two red balls are drawn

= (4C1*11C1+4C3)/15C3

= (66+4)*6/ (15*14*13)

= 70*6/ (15*14*13)

= 2/13

9) Answer: d)

Probability of picking no red balls

= 10C3/13C3

= 120/286

So, Probability of at least two red balls

= 1- 120/286

= 166/286

= 83/143

10) Answer: d)

The probability that all the balls are of different colors

= (2C1)*(4C1)*(6C1)*(3C1)/15C4

=(2*4*6*3*4*3*2)/(15*14*13*12)

= 48/455
