A tap can fill a container in 9 hours. Due to a leakage in its bottom, the container fills up in 10 hours. If the container is full, then in how much time the container will be emptied by the leakage?

A tap can fill a container in 9 hours. Due to a leakage in its bottom, the container fills up in 10 hours. If the container is full, then in how much time the container will be emptied by the leakage? Correct Answer 90 hrs

Given:

A tap can fill a container in 9 hours

With leakage container can be filled in 10 hours

Concept:

If a tap can fill a tank in x hours, then the tank filled by the tap in 1 hour = 1/x of the total tank.

Calculation:

Part of the container emptied by the leak in 1 hours = (1/9) – (1/10)

⇒ (10 – 9)/90

⇒ 1/90

∴ The required time is 90 hours.

Given below are quantities named A,B and C. Based on the given information, you have to determine the relation between the quantities. You should use the given data and your knowledge of mathematics to choose among the possible answer. Quantity A: Tap1 and Tap2 can fill the tank in 16 hours and 25 hours respectively. Both the taps opened together. After some time Tap 1 is closed and after that the tank is filled in 12 hours. In how many hour Tap 1 and 2 work together? Quantity B: Three taps 1, 2, 3 can fill a cistern in 10,14,18 hours respectively. If tap 1 is kept open all the time and tap 2 and 3 is opened alternatively for an hour then find in how many hours the tank will be filled? Quantity C: Two taps 1 and 2 are such that tap 1 fills the tank in 10 hours and tap2 empties it in 20 hours. If tap 1 is opened first and after 5 hours tap 1 is closed and tap 2 is opened, then the tank emptied in x hours and find the value of x?
There are 2 taps connected to a bucket. One tap flow hot water and other tap flow cold water. Hot water tap can fill the bucket in 15 min and cold water tap can fill the bucket in 10 min. A person opened both the tap and left the place. He returned at the time when bucket should be full but he found that due to leakage in the bottom of bucket. It is yet to be full. He reported the leakage and bucket become full in 2 minutes more, in how much time leakage can empty the bucket alone?
Tap A alone can fill the tank in 30 hours while tap B alone can fill the tank in 12 hours. Tap C empties the filled tank. When all three taps are opened then the tank gets emptied in 20 hours.

Three taps A, B & C can fill the swimming pool with uniform flow. If taps A & B are left open simultaneously, it can fill the swimming pool in the same time in which tap C alone can fill the swimming pool. However, tap B fills the pool 10 hours faster as compared to tap A and 8 hours slower as compared to tap C. In how much time tap A can fill the entire pool?
In a public bathroom there are n taps 1,2,3...n. Tap1 and Tap2 take equal time to fill the tank while Tap3 takes half the time taken by Tap2 and Tap4 takes half the time taken by Tap3. Similarly each next number of tap takes half the time taken by previous number of Tap i.e, K-th Tap takes half the time taken by (K-1)th Tap.If the 10th tap takes 2 hours to fill the tank alone then what is the ratio of efficiency of 8th tap and 12th tap, respectively?
Select the correct alternative from the given choices. Tap A can fill a cistern in 12 hours and tap B can fill the same cistern in 8 hours while tap C can empty full cistern in 10 hours. Tap A started at 9 a.m. and tap B started at 11 a.m. At what time tap C should be started such that the cistern will be half full at 1 pm?
The following questions have three statements. Study the question and the statements and decide which of the statement(s) is/are necessary to answer the question. In how many hours tap B can fill the completely empty tank? Statement I: The inlet tap A and the outlet tap C working simultaneously takes 40 hours to fill the tank. Statement II: Efficiency of inlet tap B is equal to efficiency of outlet tap C or 62.5% of the efficiency of inlet tap A. Statement III: The outlet tap C can empty a half filled tank in 12 hours.
A tank is filled by three taps A, B and C with uniform flow. Tap A and B operating simultaneously fill the tank in the same time during which the tank is filled by tap C alone. Tap B fills the tank 5 hours faster than tap A and 4 hours slower than Tap C. The time required by the Tap C is:
Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Two taps A and B can fill a tank in 12 hrs and 18 hrs respectively. Both taps are opened together but it was found that it took 108 minutes more to fill the tank due to leakage C at the bottom of the tank. Quantity A: If the tank is full, find the time in which the leakage would empty it. Quantity B: If the tap A works half its efficiency, tap B works 3/4th of its efficiency and leakage C drains double amount of water than earlier, then in what time an empty tank will get full?
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
