Question:

In 1932, I was as old as the last two digits of my birth year. When I mentioned this interesting coincidence to my Grandfather, he surprised me by saying that the same applied to him too. I thought that is impossible. However, he proved it.

Answer:

For Grandson: First Two digits of birth year: 19.

Therefore, if born in 1916, he would become 16 years in 1932

For Grandfather: First Two digits of birth year: 18.

So, 100(from 1800) +32=132

132 divided by 2 gives 66.

Therefore, if born in 1866, he would be 66 in 1932.
