Statement II The number of person's ancestors for the $10^{\text {th }}$ generation is $1024$ .

• A. Statement I and Statement II are true
• B. Statement I is true and Statement II is false
• C. Statement I is false and Statement II is true
• D. Statement I and Statement II are false

Answer 1

Answer: (C)

Total number of generations
$=\frac{\text { Total number of years }}{\text { Generation gap }} $
$=\frac{300}{30}=10$
Hence, Statement I is false.
The number of person's ancestors for the first, second, third, ...... tenth generations are $2,4,8,16,32, \ldots \ldots 1024$. Hence, Statement II is true.
