Hey! Just a heads-up — using all caps comes across a bit like shouting online. Would you mind using regular capitalization? Appreciate it!

A+B=C
Here B= 15 l/sec = 900 l/min
now A+900=C
also C>A

960 , 1860 fills the option
hence answer

Two water pumps, Pump A and Pump B, are pumping water into a partially filled tank, while a third pump, Pump C, is pumping water out of the tank. When all three pumps begin operating simultaneously, the water level in the tank does not change.

If Pump B operates at a rate of 15 liters per second, select for Rate of Pump A, the rate of Pump A in liters per minute and select for Rate of Pump C, the rate of Pump C in liters per minute that would be jointly consistent with the given information. Make only two selections, one in each column.



Rate of Pump ARate of Pump C
960
1440
1860
2280
2700

Since the water level does not change, the sum of the rates of Pump A and Pump B (inflow) must equal the rate of Pump C (outflow).

Pump B pumps at 15 liters per second = 15 * 60 = 900 liters per minute.

Checking the options:

If Pump A = 960 liters per minute, then Pump C must be 960 + 900 = 1860 liters per minute. Both values are in the answer choices. Bingo — we have our match and no need to check anything else!


Correct answer:

Rate of Pump A "960"

Rate of Pump C "1860"
