Cash ratio = (cash + marketable securities) / current liabilities
0.20 = ($10,000,000 + $2,000,000) / current liabilities
current liabilities = $12,000,000 / 0.2 = $60,000,000
Quick ratio = [cash + marketable securities + receivables] / $60,000,000
0.25 = [$10,000,000 + $2,000,000 + receivables] / $60,000,000
($60,000,000)(0.25) = $12,000,000 + receivables
$15,000,000 = $12,000,000 + receivables
$15,000,000 ? $12,000,000 = receivables
$3,000,000 = receivables
