In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: Pipe A takes thrice the time taken by Pipe B to fill a tank. Together they can fill the tank in 15 hours, tank A and B is opened together for 4 hours and then Pipe A is closed and after 2 more hours Pipe B is closed and an outlet Pipe C is opened which when working alone can empty the tank in 10 hours. Calculate the time taken by C to empty the tank. Quantity B: A pipe A can fill the tank in 10 hours another pipe B can fill the tank in 15 hours and with the help of third pipe C they can fill the tank in 5 hours. Pipe A is opened for 4 hours then it is closed, pipe B is closed 3 hours before filling of tank and tank C is opened the whole time. Calculate the time taken to fill the tank

A

Quantity A > Quantity B

B

Quantity A < Quantity B

C

Either Quantity A = Quantity B or no relation can be established

D

Quantity A ≥ Quantity B

E

Quantity A ≤ Quantity B

In the question below, is given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the suggested courses of action logically follow (s) for pursuing. Statement: The numbers are impressive. In its quest towards Swachh Bharat, the government has built 4.98 crore rural household latrines in the last three years. What's more, recent surveys by the NSSO and the Quality Council of India show that over 90% people with access to toilets are using them. Launched with the idea of Clean India, it is expanding from urban to the rural areas and is spreading awareness among the masses. Courses of action: I. Given that most rural areas in India lack proper drainage and a sewage network, the government has focused on building twin-pit toilets. But there is no data on whether the size of hastily built twin pits takes into account the number of users, and whether each pit is enough to collect waste for three years. II. While this is a positive indicator, there are many other areas that need attention such as the shortage of water, sensitization of citizens, proper maintenance and usage of toilets, and overcoming the resistance to dry manure made from human waste. III. One of the biggest challenges for Swachh Bharat in rural areas is managing liquid waste, which pollutes natural water bodies. Though the scheme covers this aspect as well, the immediate focus is to deal with open defecation.

A

Only III follows

B

Neither II nor III follows

C

None follows

D

All except III and I

E

1996-7 and 2002-3, the area under canal irrigation declined by 2.4 million ha (13.8 percent), the area under tank irrigation fell by 1.4 million ha (42.4 percent), and the area irrigate by all other sources declined by 1 million ha (28 percent). The only irrigation source that increased its share was groundwater wells, by 2.8 million ha (more than 9 percent) Why has such a change in irrigation demands happened? 1. Not enough supply of water from canals 2. More tubewell irrigation by farmers in the source areas of rivers 3. High cost of irrigation water, and diversion for non-farm use 4. Joint use of water not possible due to social and economic inequalities

Two pipes are connected to tank 1 and one pipe connects tank 1 and tank 2 at the bottom of both tanks. At first pipe A and pipe B will filling tank 1 and then pipe C would be opened to fill tank 2. Capacity of tank 1 is twice capacity of tank 2. Pipe C takes 8 minutes to fill the whole tank 2 wherein discharging capacity of pipe C is 62.5 liters per minute. Ratio of time taken by pipe A and B to fill the tank when operating alone is 4 : 5 then find approximate discharging capacity of pipe A and B in liters/ minute if both the pipes discharge equal amount of water in tank. Time taken by pipe A and B to fill the tank 1 is 20/ 3 minutes

A

38 liters/ minute, 30 liters/ minute

B

42 liters/minute, 33 liters/ minute

C

44 liters/ minute, 31 liters/ minute

D

41 liters/ minute, 30 liters/ minute

E

45 liters/ minute, 28 liters/ minute

Three pipes x, y and z can fill a tank A can fill it in 4 minutes. Two pipes p and q are connected to tank B. how much time does it take for both tanks to run at the full capacity? Ratio of time taken to fill tank A by P and time taken by x to fill tank A is 2: 1 and ratio of time taken by Q to fill tank B and Z to fill tank A is 5: 3. Pipe P is 20% more efficient then pipe Q. and pipe Y takes 12 minutes to fill the tank. Capacity of tank B is 3/4 times of tank A. Note: Tank B is to be filled only after filling tank A. Valves of pipe p and q are closed once tank B is running at full capacity.

A

18 minutes

B

163/ 9 minutes

C

172/ 9 minutes

D

20 minutes
