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
