Answer:

The twins would be 13 years old.

Step-by-step explanation:

21+21+21+13+13 = 89
The twins are 13
I did it by seeing that 89 ended in 9
So I figured the triplets ages had to end in 3 when all combined.
I tried different things and then eventually got 21 x 3 = 63 and 89 - 63 = 26 lastly 26/2=13
Let me know if that was right :)
