A child said that his age in years was equal to the last two digits of his birthyear. The child's grandmother said the same thing.

If they both said it in 1932, how old are were they at the time?

The child's age is easy. Half of 32 is 16. So he was born in 1916 and was 16 when he made the statement.

For granny's age, we can start from 1800. That was 132 years previously. Half of 132 is 66, so granny was born in 1866 and was 66 when she made the statement.
