I’m not clear, either. When you calculate the current ratio with given info in year 2007, it’s 0.77. If you multiply this by 1.5, you get the answer you refer to, 1.16. I found that by accident. I’m not sure why you would multiply by 1.5.
If the base year current ratio is 1.5, then assume that current assets were, say, 15 and current liabilities were 10. Then in 2007, current assets would be 15 × 101.4% = 15.21, and current liabilities would be 10 × 131% = 13.10; the current ratio would be 15.21 / 13.10 = 1.16.
