Subtracting equal current amounts leaves the difference unchanged, while the ratio changes from 120/80 to 100/60.
The payment also removes $20,000 Cash from current assets, so both sides of the difference fall equally.
A constant difference does not imply a constant quotient; $100,000 divided by $60,000 is about 1.67.
The ratio movement and claim settlement are facts, but remaining maturities, inflows, restrictions, and funding access are needed for a capacity conclusion.
Answer: A
Before payment, working capital is $40,000 and the current ratio is 1.50. After reducing Cash and Accounts Payable by $20,000, current assets are $100,000 and current liabilities are $60,000. Working capital remains $40,000 and the ratio is approximately 1.67. Choice A is correct; the direction alone does not prove practical liquidity improved.
