The multiples of 6 that are between 30 and 70 are:
30, 36, 42, 48, 54, 60, 66
The multiples of 5 that are between 30 and 70 are:
30, 35, 40, 45, 50, 55, 60, 65, 70
We can see that 54 & 55 are from the first and second set respectively. These values are 1 unit apart.
If Chloe is 54 now (a multiple of 6), then next year she is 55 (a multiple of 5).
Four years from now she will be 54+4 = 58
Answer: 58
