bitex2: SOLUTION to the second part of the quest
let the no of y be p
n+p=(m+p)/2 + 3
n+p=(2n+38+p)/2 + 3
2n+2p=2n+38+p+6
p=44
therefore in 44yrs the niece age will satisfy the statement that it is 3 more than half his uncle's age

jaryeh: To Maximus' question.

let the age of the man be m,and his niece' be n.

therefore,from the 1st statement
m = 2n+38 .....eqn(i)
2nd statement
n^2-m =42 ....eqn(ii)

To solve eqns(i) and (ii) simultaneously,substitute 2n+38 for m in eqn (ii),
hence, n^2 -(2n+38)=42

n^2 -2n-38=42

n^2 -2n-80=0

(n+ (n-10)=0
therefore,n=-8 or n=10,but age can't be negative,hence n=10

by substituting 10 for n in eqn (i)

m=2(10) +38
m=58.

therefore the man's present age is 58,while his niece' is 10.

then,to the first part of the question,the closest perfect square to 58 is 64,that will mean an addition of extra 6yrs,which if added to the niece' age will give 16 which is also a perfect square. Hence,their ages would simultaneously be perfect squares in the next 6 yrs

Richiez: This is the correct answer to my question
