About 53 years old
My grandson is about as many days as my son is weeks. And my grandson is as many months as I am in years. My grandson, my son, and I together are 140 years. Can you tell me my age in years?
On my birthday in 2021, my age is equal to the sum of the digits of my birth year. I am less than 100 years old. What could my birth year be?
