Answer:
Nan will have more money than Neal at any age.
Explanation:
There are 5 major key points that must be identified from the question:
1. Nan and Neal are twins: Hence they are same age
2. Nan invests at age 25: 5 years earlier than Neal who invest at 30
3. Both of them invests same amount at same interest rate
4. Both investment compounds annually
5. Both twins retire at age 60 and neither adds nor withdraws funds prior to retirement
From this key points, it is clear that with the 5 years investment gap, Nan will surely have more money than Neal at any point in time, since all the factors of investment for both are the same, with Nan having the advantage because of the early-bird factor. He would definitely have over 5000 dollars as at the time Neal would start, and Nan's value at the starting year of Neal, would be Neal's amount in 5 years time, and at that time, Nan would be ahead, since they both compound annually.
