I do not think there is any error here,
Since, "at" is a preposition, we need a noun to be its object i.e 14,000.
refer this : https://www.beatthegmat.com/sc-with-surf ... 43734.html - "estimated at" in the non underlined portion.
Hope this helps !!

The crowd estimated to be 14,000 - this is what will happen to Noun (not sensible here as the crowd is already dispersed)

Yes, exactly Patanjali.
After the tsunami, Japan's Insurance loses estimated to be XX $.
- since an infinitive is used for something indefinite in the future - here it signifies XX$ is not the exact value , there is some variation
After the tsunami, Japan's Insurance loses estimated at XX $ -- the value is confirmed, no variation is there.
In OG-12 #27, since a range is given (40 to 44 million years) "to be" is right.

this is one of those instances in which the OG explanation is inaccurate. (that happens infrequently, but not as infrequently as one might hope.)mankey wrote:The OG says "estimated to be" is the right idiom and not "estimated at".
fortunately, what's happening is pretty simple: "at" is a preposition, and so (like other prepositions) needs to have a noun as its object.
"40 to 44 million years old" is not a noun, so, wrong.
(if the sentence had said something like The age of xxxx was estimated at 40 to 44 million years, then that version would be fine.)
as proof, consider the following from GMAT PREP:
With surface temperatures estimated at minus 230 degrees Fahrenheit, Jupiter's moon Europa has...
estimated at + noun ... again, no problem.

* "at" is a preposition.
* prepositions must be followed by nouns.
* "xxx number of years old" is not a noun.
so, wrong.
in the other example -- "temperatures estimated at xxxx degrees fahrenheit" -- there's no problem, because "xxxx degrees fahrenheit" is a noun.
i don't think anything else is happening here.
the OG explanations are wrong fairly regularly (though not in most cases); this is one of those times.
The bolded portion is written by Ron Purewal in MGMAT forums
So i have the following doubt regarding noun placements after prepositions.
In OG 13 Q140 (not typing the question)
how come dated to be 347 billion years old is wrong but dated at 347 billion years is correct?
Am i thinking in the wrong direction?

TO BE in "to be 347 billion years old" is an INFINITIVE and therefore Ron's thought about AT (a preposition) does not apply here. Also OLD is an adjective (not noun)
dated at 347 billion years (AT = prep; YEARS = noun)
