To fill a tank measuring 20 cm by 40 cm by 22 cm completely, it takes Tap G 33 minutes while it takes Tap H only 33 minutes. How long will it take to completely fill the container with water if both the taps are turned on at the same time and 5 cubic containers of edges 8 cm, filled to the brim with water are poured into the tank? Leave your answer in minutes and round off to 2 decimal places.
Volume of the tank 
= 20 x 40 x 22
= 17600 cm³
= 17600 mℓ

Volume of 5 containers
= 8 x 8 x 8 x 5
= 2560 cm³ 
= 2560 mℓ

Remaining volume to be filled by the Tap G and Tap H 
= 17600 - 2560
= 15040 mℓ
= 15040 cm³

Fraction of the tank to be filled
= ¹⁵⁰⁴⁰₁₇₆₀₀
= ⁴⁷₅₅

Tap G:
1 tank → 33 min
1 min → ¹₃₃ tank

Tap H:
1 tank → 33 min
1 min → ¹₃₃ tank

Tap G and Tap H:
1 min → ¹₃₃ + ¹₃₃ = ¹₃₃ + ¹₃₃ = ²₃₃ tank

1 tank = ³³₂ min

⁴⁷₅₅ tank = ³³₂ x ⁴⁷₅₅ = ¹⁴¹₁₀ = 14.1

Answer(s): 14.10 min
