To fill a tank measuring 60 cm by 30 cm by 32 cm completely, it takes Tap K 27 minutes while it takes Tap L only 27 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 7 cubic containers of edges 12 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 
= 60 x 30 x 32
= 57600 cm³
= 57600 mℓ

Volume of 7 containers
= 12 x 12 x 12 x 7
= 12096 cm³ 
= 12096 mℓ

Remaining volume to be filled by the Tap K and Tap L 
= 57600 - 12096
= 45504 mℓ
= 45504 cm³

Fraction of the tank to be filled
= ⁴⁵⁵⁰⁴₅₇₆₀₀
= ⁷⁹₁₀₀

Tap K:
1 tank → 27 min
1 min → ¹₂₇ tank

Tap L:
1 tank → 27 min
1 min → ¹₂₇ tank

Tap K and Tap L:
1 min → ¹₂₇ + ¹₂₇ = ¹₂₇ + ¹₂₇ = ²₂₇ tank

1 tank = ²⁷₂ min

⁷⁹₁₀₀ tank = ²⁷₂ x ⁷⁹₁₀₀ = ²¹³³₂₀₀ = 10.665

Answer(s): 10.67 min
