Two tanks are of the same capacity when fully filled. Tank A emptiescompletely in 3 hours while Tank B empties in 5 hours. When will thewater level in one tank be twice the water level in the other tank? About the author Eva
Answer: Let height of water level in each tank be x cm. Tank A is completely filled, Now, some water is poured from tank A to tank B ∴ Volume of remaining water in tank A = 15×15×x cubic.cm Now, volume of water in tank B = 25×11×x cubic.cm Volume of tank A = Volume of remaining water in tank A + volume of water in tank B 15×15×20 =(15×15×x)+(25×11×x) ∴ 4500=225x+275x ∴ 500x=4500 ∴ x=9 cm ∴ Height of water level in each tank is 9 cm.

Answer:
Let height of water level in each tank be x cm.
Tank A is completely filled,
Now, some water is poured from tank A to tank B
∴ Volume of remaining water in tank A = 15×15×x cubic.cm
Now, volume of water in tank B = 25×11×x cubic.cm
Volume of tank A = Volume of remaining water in tank A + volume of water in tank B
15×15×20 =(15×15×x)+(25×11×x)
∴ 4500=225x+275x
∴ 500x=4500
∴ x=9 cm
∴ Height of water level in each tank is 9 cm.
