There are 3 discharge pipes A, B and C in a pool, A can discharge 100 liters of water per hour, and B can discharge 125 liters of water per hour. Now use A to discharge water first, and after 2 hours, start to use B pipe again, and then open C pipe after a while, let A, B, and C pipes release water at the same time until the water is drained. Calculate the amount of water discharged from pipes A, B, and C, and find that they are exactly equal. So how much water was there in the pool?
某水池有甲、乙、丙3个放水管，每小时甲能放水100升，乙能放水125升．现在先使用甲放水，2小时后，又开始使用乙管，一段时间后再开丙管，让甲、乙、丙3管同时放水，直到把水放完．计算甲、乙、丙管的放水量，发现它们恰好相等．那么水池中原有多少水？
