Your example is not consistent.
Your table A:D states that 60 or more should return "60+years"
In your Desired output I find "60+years", "60 years" ( although the outcome is 62) and "70 years" ???
To stick exactly to your table try
=VLOOKUP(MIN(FLOOR(DATEDIF($G2,TODAY(),"y"),10),60),$C$2:$D$7,2,0)
which should work on all XL versions
