He was 100 years old.

60 + 60 plus 30 is equal to 150, and the calculation process is as follows:

60 + 60 plus 30 = 60 + 60 + 30 = 120 + 30 = 150

Of course, 60 is close to 100.

Let's think about whether 6 is close to 10 or 4 is close to 10, 10-6=4, 10-4=6, 4 6, so 6 is close to 10.

In the same way, 100-60 = 40, 100-40 = 60, 40 60, so the air loss of 60 is closer to 100.

Is 600 close to 1000 or 400 close to 1000, the fighting god wants to reduce the number of two, and he has to count who is smaller and who is close.

So 600 is close to 1000.
