Pipe a fills a tank of capacity liters at the rate of liters a minute. Another pipe b fills the same tank at the rate of liters a minute. A pipe at the bottom of the tank drains the tank at the rate of liters a minute. If pipe a is kept open for a minute and then closed and pipe b is open for a minute and then closed and then pipe c is open for a minute and then closed and the cycle is repeated, when will the tank be full?

Calculated Answer

45

Step by Step Solution

In order to solve problem, you must evaluate n₀ / (n₁ + n₂ - n₃) * 3.

• n₀ / (n₁ + n₂ - n₃) * 3

• Evaluate n₁ + n₂ = 70

  n₀ / (70 - n₃) * 3

• Evaluate 70 - n₃ = 50

  n₀ / 50 * 3

• Evaluate n₀ / 50 = 15

  15 * 3

• Evaluate 15 * 3 = 45

  45
• The answer to the problem and the result of n₀ / (n₁ + n₂ - n₃) * 3 is 45
