Question 23
A tank measuring 28 cm by 20 cm by 30 cm was filled with 5000 cm$^3$ of water. At 2 p.m., water was continuously added into the tank at a constant rate of 25 cm$^3$ every minute. At 3 p.m., 200 cm$^3$ of water was drawn out of the tank and subsequently, a further 200 cm$^3$ was also drawn out at the end of every hour after. At what time did the tank start to overflow for the first time? (Express your answer in HHMM format of the 24-hour clock. For example, 4 a.m. represented as 0400; 4.25 p.m. represented as 1625.)
