Time (in minutes)
Lesser the number of pipes more will be the time required by it to fill the tank. So, this is a case of inverse proportion. Thus, time taken to fill the tank by 5 pipes is 96 minutes or 1 hour 36 minutes

6 pipes are required to fill a tank in 1 hour 20 minutes. How long wil...
To solve this problem, we can use the concept of work done. The work done by a pipe is directly proportional to the time it takes to fill the tank. Let's break down the solution into steps:
Step 1: Calculate the work done by 6 pipes
Since 6 pipes can fill the tank in 1 hour 20 minutes, we need to convert this time into minutes. 1 hour is equal to 60 minutes, so 1 hour 20 minutes is equal to 60 + 20 = 80 minutes.
Let's assume that the work done by each pipe in 1 hour 20 minutes is W. Therefore, the total work done by 6 pipes is 6W.
Step 2: Calculate the work done by 1 pipe
To find the work done by 1 pipe, we divide the total work done by 6 pipes by 6: W = (6W)/6 = W.
So, the work done by 1 pipe is W.
Step 3: Calculate the time taken by 5 pipes
Now, we need to find the time taken by 5 pipes to fill the tank. Let's assume that the time taken by 5 pipes is T.
Since the work done by 1 pipe is W, the work done by 5 pipes in time T is 5W.
Step 4: Calculate the time in minutes
We can set up a proportion to find the time T:
6 pipes take 80 minutes to fill the tank
5 pipes take T minutes to fill the tank
Using the proportion: 6/5 = 80/T
Cross-multiplying, we get: 5 * 80 = 6T
Simplifying, we get: 400 = 6T
Dividing both sides by 6, we get: T = 400/6 = 66.67 minutes
Step 5: Round the answer
Since the given options are in minutes, we need to round the answer to the nearest minute. Therefore, the time taken by 5 pipes to fill the tank is approximately 67 minutes.
Step 6: Check the options
Among the given options, option C) 96 minutes is the closest to our answer of 67 minutes.
Therefore, the correct answer is option C) 96 minutes.
Step 1: Calculate the work done by 6 pipes
Since 6 pipes can fill the tank in 1 hour 20 minutes, we need to convert this time into minutes. 1 hour is equal to 60 minutes, so 1 hour 20 minutes is equal to 60 + 20 = 80 minutes.
Let's assume that the work done by each pipe in 1 hour 20 minutes is W. Therefore, the total work done by 6 pipes is 6W.
Step 2: Calculate the work done by 1 pipe
To find the work done by 1 pipe, we divide the total work done by 6 pipes by 6: W = (6W)/6 = W.
So, the work done by 1 pipe is W.
Step 3: Calculate the time taken by 5 pipes
Now, we need to find the time taken by 5 pipes to fill the tank. Let's assume that the time taken by 5 pipes is T.
Since the work done by 1 pipe is W, the work done by 5 pipes in time T is 5W.
Step 4: Calculate the time in minutes
We can set up a proportion to find the time T:
6 pipes take 80 minutes to fill the tank
5 pipes take T minutes to fill the tank
Using the proportion: 6/5 = 80/T
Cross-multiplying, we get: 5 * 80 = 6T
Simplifying, we get: 400 = 6T
Dividing both sides by 6, we get: T = 400/6 = 66.67 minutes
Step 5: Round the answer
Since the given options are in minutes, we need to round the answer to the nearest minute. Therefore, the time taken by 5 pipes to fill the tank is approximately 67 minutes.
Step 6: Check the options
Among the given options, option C) 96 minutes is the closest to our answer of 67 minutes.
Therefore, the correct answer is option C) 96 minutes.
