7. A water tap fills water at the rate of [tex]25 \, L[/tex] per minute into a water tank. Another water tap can fill water in the same tank at the rate of [tex]15 \, L[/tex] per minute. If both the water taps are opened, then the water tank is filled in 15 minutes. Find the volume of the water tank.



Answer :

Sure! Let's solve this problem step-by-step.

1. Identify the rates at which the taps fill water:
- The first tap fills water at a rate of [tex]\( 25 \)[/tex] liters per minute.
- The second tap fills water at a rate of [tex]\( 15 \)[/tex] liters per minute.

2. Determine the combined rate of both taps:
- When both taps are open, their rates will add up. So, the combined rate at which both taps fill the water tank is [tex]\( 25 + 15 = 40 \)[/tex] liters per minute.

3. Determine the time taken to fill the tank:
- Both taps are opened for [tex]\( 15 \)[/tex] minutes.

4. Calculate the volume of the water tank:
- The volume of the water tank can be found by multiplying the combined rate of water flow with the time both taps are open.
[tex]\[ \text{Volume of the water tank} = \text{Combined rate} \times \text{Time} \][/tex]
[tex]\[ \text{Volume of the water tank} = 40 \, \text{liters per minute} \times 15 \, \text{minutes} \][/tex]
[tex]\[ \text{Volume of the water tank} = 600 \, \text{liters} \][/tex]

Therefore, the volume of the water tank is [tex]\( 600 \)[/tex] liters.
