Question

Madhav went to a wedding along with his parents. He met many relatives there. But he didn’t know everyone. He met his mother s grandfather but found that her grandmother is not alive. He also found that her mother (grandmother s mother) is still alive, and is more than a hundred years old.
Madhav got confused. He couldn’t imagine his mother’s grandmother’s mother! So, Madhav’s mother made a family tree for him —

Madhav’s mother helped him understand her family with the help of this drawing. You can also find out about your older generations using such a family tree

Answer these question:

• If he takes his family tree forward in which generation will he find 128 elders?

Answer 1

• Number of members in VII generation of Madhav’s family = 32
• Number of members in VIII generation of Madhav’s family
  = 32 × 2
  = 64
• Number of members in IX generation of Madhav’s family
  = 64 × 2
  = 128

Thus, in the IX generation, the number of elders in Madhav’s family will be 128.
