A tank with capacity T liters is empty. If water flows into the tank from pipe X at the rate of x liters per minute and water is pumped out by Y at the rate of y liters per minute and x > y, then how many minutes will the tank be filled?
A. (x - y) 60 T minutes
B. (T - x) minutes
C. $$\frac{{\text{T}}}{{{\text{x}} - {\text{y}}}}$$ minutes
D. $$\frac{{\text{T}}}{{{\text{y}} - {\text{x}}}}$$ minutes
Answer: Option C
Solution (By Examveda Team)
Net volume filled in 1 minute= (x - y) liters
∴ The tank will be filled in
= $$\frac{{\text{T}}}{{\left( {x - y} \right)}}$$ minutes
