let the number be a and b,
now according to given conditions...
a+b=28
and
(a+b)/2 = √(a*b)
( since geometric mean is equal to square root of product of two number)
28/2=14=√(a*b)
squaring both sides
14*14=7*2*7*2=a*b
the possible combinations are 49*4=a*b
as 49 and 4 are perfect squares so,
49+4=53
so option 7 is correct
