Answer: 60 inches

Step-by-step explanation:

Let x be the height of son in the beginning of the year.

If the height is increased 110% at the end of the year , then his height in the end of the year = 110% of x

$=1.1x$ [since 110%=1.1]

Since, his height at the end of the year = 66 inches

$\\\Rightarrow\ 1.1 x=66\\\Rightarrow\ x=\frac{66}{1.1}=60$

Hence, the height of Mrs. Peters son in the beginning of the year is 60 inches.
