### 67 Per Cent (67 What Per Cent?)

The power of the "headline" never ceases to amaze.

The following headline was seen on FT.com (Financial Times) website.

```   Google revenues surge 67 per cent
```

Question: 67 what per cent? Revenues are typically in units of dollars, but 67 dollars per cent doesn't make sense.

The posting for the headline started as follows.

```   "Google's net revenues surged 67 per cent in the
final quarter of last year, ahead of estimates."
```

If we assume the "per cent" is suppose to be "percent," it prompts the question: 67 percent when compared to what? Net revenues could be up 67% compared to the previous quarter or they could be up 67% compared to the same quarter a year ago or they could be up 67% from estimates.
