Choose the correct option.

An empty tank be filled with an inlet pipe A in 42 minutes. After 12 minutes an outlet pipe B is opened which can empty the tank in 30 minutes. After 6 minutes another inlet pipe C opened into the same tank, which can fill the tank in 35 minutes and the tank is filled. Find the time taken to fill the tank?

A45.5 mins

B50.5 mins

C58.5 mins

Dnone of these

Explanation:

For first 12 mins tank is 2/7 filled
For first 18 mins tank is 8/35 filled. i.e pipe A is opened for 18 mins and pipe B is opened for 6 mins. (3/7)-(1/5)=8/35. that means after 18 mins tank is 8/35 filled.
so, after 18 mins all the 3 pipes work simultaneously.
Now calculate the time required to fill the tank by 3 pipes,
(1/42)+(1/35)-(1/30)=2/105. It means 105/2 mins.
But the tank is already 8/35 filled.
The time taken to fill 27/35 of the tank=(105/2)*(27/35)= 40.5 mins.
The time taken to fill the tank= (18+40.5) mins = 58.5 mins.

Choose the correct option.

The water from one outlet, flowing at a constant rate, can fill the swimming pool in 9 hours. The water from second outlet, flowing at a constant rate can fill up the same pool in approximately in 5 hours. If both the outlets are used at the same time, approximately what is the number of hours required to fill the pool?

A3.21 hrs.

B3.34 hrs.

C2.32 hrs.

DNone of these

Explanation:

Lets assume tank capacity = x Liters.
Given:
First pipe fills the tank in 9 hours.
So first pipe capacity = x/9 Liters/ Hour.
Second pipe fills the tank in 5 hours.
So its capacity is x/ 5 Liters/Hour

Condition: If both pipes are opened together
number of hrs. required to fill a tank of capacity x liters = x/(x/5+x/9) = x/(14x/45) = 45/14 = 3.21 hrs.

Choose the correct option.

Two pipes A and B can fill a tank in 4 hours and 5 hours respectively. If they are turned up alternatively for one hour each,then time taken to fill the tank is:

A2 hrs 15 mins

B4 hrs 24 mins

C5 hrs

D3 hrs

Explanation:

L.C.M of 4hr and 5hr will be 20units. (tank size)
Given. pipe A and B fill a tank in 4 hrs and 5 hrs res.
So, A can fill 5u in 1hr and B can fill 4u in 1hr.
(5u+4u)+(5u+4u)=18u in 4hr (alternatively opend)
Remaining 2u will be filled by pipe A
5u will take=60mins
Hence 1u =60/5min=12mins
Hence 2u will take 12*2=24mins.
Total time required = 4 hrs. + 24 min.

Choose the correct option.

Two pipes A and B can fill a tank in 20 and 30 minutes respectively. If both the pipes are used together, then how long will it take to fill the tank?

A12 min

B15 min

C25 min

D50 min

Part filled by A in 1 min = 1/20
Part filled by B in 1 min = 1/30.
