This post is a part of Project IR Butler 2019-20. Click here for Details

Two water storage tanks, Tank A and Tank B, can each hold more than 20,000 liters of water. Currently, Tank A contains 5,000 liters of water, while Tank B contains 8,000 liters. Each tank is being filled at a constant rate, such that in 15 hours, the two tanks will contain the same amount of water, though neither will be full.

In the table below, identify rates of filling for each tank that are together consistent with the information. Make only one selection in each column.

 Tank A fill rate Tank B fill rate Values 30 liters/hr 90 liters/hr 150 liters/hr 220 liters/hr 290 liters/hr

Spoiler: :: OA
 Tank A fill rate Tank B fill rate Values 30 liters/hr Tick 90 liters/hr 150 liters/hr 220 liters/hr Tick 290 liters/hr

5000+ 15x = 15y+ 8000

x-y= 200

So B is 90
A = 290
