An empty rectangular tank has a capacity of 97 ℓ and a height of 200 cm. At 6 a.m., Tap C is turned on to fill the tank at a rate of 8 ℓ per minute for 19 minutes. After 13 minutes, Tap D is turned on to drain water from the tank at a rate of 2 ℓ per minute for 27 minutes. What is the height of the water level in the tank in the end? Give the answer in 1 decimal place.
1 ℓ = 1000 cm³ 
8 ℓ = 8000 cm³ 
2 ℓ = 2000 cm³ 
97 ℓ = 97000 cm³

Volume of water flowed in from Tap C
= 19 x 8000
= 152000 cm³

Volume of water from drained from Tap D
= 27 x 2000
= 54000 cm³

Volume of water left in the tank
= 152000 - 54000
= 98000 cm³

Base area of the tank
= 97000 ÷ 200
= 485 cm² 

Height of water left in the tank
= 98000 ÷ 485
≈ 202.1 cm

Answer(s): 202.1 cm
