Answer:
There will be 5 liters of water in the jar at the end of 15 minutes.
Step-by-step explanation:
A jar containing 50 liters of water is fitted with an inlet pipe and an outlet pipe. Water is flowing into the tank at 1 litre per minute and water is flowing out at 4 litres per minute.
How much water will be there in the jar at the end of 15 minutes?
The water outflow and inflow are 4 litres and 1 litres per minute.
Let us represent the inflow = (+1)L
=>The outflow = (−4)L. (drains the jar)
The net amount of water added in one-minute = (−4)L + (+1)L = (−3)L
=> 3L of water is drained from the jar in every minute.
The amount of water added in 15 minutes = 13 × (− 3)L = (− 45)L
=> 45L of water is drained from the jar in 15 minutes.
Add (− 45) L and 50 L (the amount of water in the jar available initially)
=> (− 45) L + 50 L = 5L
There will be 5 litres of water in the jar at the end of 15 minutes.
