Every man or woman alive today had 2 parents, 4
grandparents, 8 great – grand parents, 16 great great- grand parents, 32 great,
great, great grandparents and so on.
Let us take the case of Ram. Two generations ago Ram had 2 x
2 or 2², or 4 ancestors. Three generations ago he had 2 x 2 x 2 or 2ᶾ or 8
ancestors. Four generations ago he had 2 x 2 x 2 x 2 or 2⁴ or 16 ancestors.
Assuming that there are 20 years to a generation; can you
tell 400 years back how many ancestors did Ram have?
Answer: 1048576 - 400 years ago, that is 20
generations back, ram – for that matter each one of us had 2²⁰ or 1048576
ancestors.
