Question:medium
2 pipes can fill a tank in 10 minutes together. If the efficiency of the first pipe is 8 times the efficiency of the second pipe, find the time required to fill the tank using the second pipe alone.
2 pipes can fill a tank in 10 minutes together. If the efficiency of the first pipe is 8 times the efficiency of the second pipe, find the time required to fill the tank using the second pipe alone.
Show Hint
When efficiency is given as a multiple "n", the time for the slower pipe alone is always \(\text{Together Time} \times (n + 1)\). Here: \(10 \times (8 + 1) = 90\).

- A town is supplied with water from a big overhead tank which is fed with a constant volume of water regularly. When the tank is full, if 32000 gallons are used daily, the supply fails in 50 days. However, if 37000 gallons are used daily, the supply lasts for 40 days only. How much water can be used daily without the supply ever failing?
