47





The highest (odd perfect square - 2) less than 55.





If the "oldest" restriction were not present, then 23, 7 and 2 would also be possible answers. Once we get past 2, we are only interested in odd perfect squares since the prime #s %26gt; 2 are all odd.
Reply:May be 23years or 47 years





23 and 47 are both prime numbers





after 2 years both will become perfect square - 25 and 49





The oldest person this year is at the age of 47years.
Reply:Hattie is not yet 55 years of age, so let's find the first perfect square less than 55. That number is 49 (7x7). Two less than 49 is 47 which is a prime number - voila! That's the answer! Hattie is now 47 years old.
Reply:47 as nearest perfect square is 49.
Reply:The highest perfect square below 55 is 49, and 2 less than 49 is 47, which is prime... so Hattie is 47.
Reply:Hattie at prime age now and


a perfect square age in 2 years


He's less than 55 years old





so he's 47 years now, in 2 years he'll be 49.
Reply:47 (7 x 7 is 49, minus 2)
Reply:hattie can be either 23 or 47,but as you said oldest,hattie is now 47.


47 is a prime no.


47+2=49(7*7)


Thus,47+2=49, is a perfect square.


thats why hattie is now 47
Reply:hattie will retire at 55 so her age is less than 55





perfect sqaure age less than 55 are 49,36,25 but





49-2=47 is prime


36-2=34 isn't prime


25-2=23 is prime





as hattie is 47 or 23 this year
Reply:well everyone else seems to be on the right track so there is really no need for me to answer the question right!!!
Reply:At 55 Hatties will retire, means he hasn't.


So he must be less than 55.


Looking at all the prime numbers below 55 backwards.


53, 51, 47, 43, 41, 37, ........


I would say 47.


coz 47 is a prime number, and 47+2=49, which is 7*7.
