6. Directions(6-10):
Study the following graph and answer accordingly
The following line graph shows the Time taken by four pipes to full an empty tank. The following table shows the comparison of efficiency between A,B,C ,D and to P,Q,R,S(either
inlet or outlet). 7. Four pipes C,D,P and Q can fill a tank . When initially the tank is empty pipes C, D, P and Q start to fill the tank .After two hours pipe C is closed, after another 1hour pipe D is closed and Pipe P is closed 2 hours before the tank is full and the remaining part is filled by pipe Q alone .Find the time taken by all the pipes together to fill the tank.

Option D
2/ 60 + 3 /15 + (𝑥 – 2)/ 15 + 𝑥/ 30 = 1
[2 + 12 + 4𝑥 − 8 + 2𝑥 ]/60 = 1
=> 6x + 6=60
=> 6x=60-6=54
=> X=54/6 = 9 hrs

8. Initially two inlet pipes A and D are opened for two hours and the remaining part is filled by pipe Q alone .Find the time taken by pipe Q to fill the remaining tank?

22
Option B
(A+D)’s one hour= 1 /30 + 1 /15 = 3/ 30
= 1/ 10
For 2 hours = 1/ 5
Remaining part of the tank=1 – 1/ 5 = 4 /5
Remaining tank is filled by Q alone in 4/ 5 × 30 = 24 ℎ𝑜𝑢𝑟

9. Two inlet pipes A and B fill the tank and two outlet pipes R and S empty the tank. All the four pipes are opened together. Find the time taken to full the tank.

Option A
1/ 30 + 1/ 15 – 1/ 20 – 1/ 60
= 1 [2 + 4 − 3 – 1]/ 60
= 1 [ 6 – 4]/ 60 = 1
= 1/ 30 ℎ𝑜𝑢𝑟𝑠 = 30ℎ𝑜𝑢𝑟

10. Find the time taken to fill the tank when all the inlet pipes A,B,C and D are opened together and also when two outlet pipes P and Q are opened together.

Option D
A ,B ,C and D one hour work
= 1 /30 + 1 /60 + 1 /15 + 1/ 15 = 11 /60 𝑝𝑎𝑟𝑡
=> 60/ 11 ℎ𝑜𝑢𝑟𝑠
P=2A
Efficiency ratio of P:A=2:1
Time taken ratio=1:2
P=15days
Q=(1/2)×B
Time taken ratio of B and Q=2:1
Q=30 hours
P+Q’s one hour work= 1/ 15 + 1/ 30 = 1/ 10 𝑝𝑎𝑟𝑡
One hour work of A,B,C,D,and P and Q
= 11 /60 – 1/ 10 = 5/ 60 = 12 ℎ𝑜𝑢𝑟s

11. Initially both the pipes A and C are opened together to fill a tank and when the tank was 1/3rd full ,a leak developed, through which 1/ 4 𝑡ℎ of the water supply by both the pipes leaked out .Find after how many hours the tank be full.
17 (3 /8 )
16 (5 /9 )
17 (7 /9 )
10 (2 /7 )
11 (5/9 )
Option C
Let total work be 60 units
A=2units
C=1units
A+C=3units
Leakage= (1+2)*1/4=-3/4
A+C-leak=2 + 1 − 3 /4 = 9 /4
A+C=60 × 1/ 3 = 20 units
Remaining = 40 units
𝑇𝑖𝑚𝑒 = 40 /9/ 4 = 160/ 9 ℎ𝑜𝑢𝑟𝑠
= 17 (7 /9 ) ℎ𝑜𝑢𝑟𝑠

Thanks for sharing your ideas. I would also like to mention that video games have been ever evolving. Technology advances and enhancements have helped create authentic and interactive games. These types of entertainment games were not actually sensible when the concept was first being used. Just like other areas of technologies, video games also have had to grow as a result of many decades. This is testimony towards fast continuing development of video games.
