in complete tree with 5 level,each node have 4 child or no child ,how many node in the tree,
option
1>321 2>256 3>1024 4>non of these .

• 1024 because
  when node have 4 child (4^h)-1=(4^5)-1=1023
  now when node have 0 child then there will be only 1 node
  so 1023+1=1024

• as in binary tree we take (2^h)-1 and for explanation if h=1, number of nodes in binary tree is 1. (i.e true).
  But,
  in case of 4-ary tree if we take (4^h)-1 and for explanation if h=1, number of nodes in this tree is 3. (i.e false). thats why we cant use this formula.
  correct answer is 4^0+4^1+4^2+4^3+4^4 = 341

• If a binary consists od two child rens and haing heigh h ;then the no of nodes are as we know 2 pow h -1.like here we having 4 Childs.Just apply.SIddarth is right

• ans is d) non of these
  levels n=5,each node have 4 child
  so
  4^(5-1)=4^4
  =4^0+4^1+4^2+4^3+4^4
  =1+4+16+64+256=341

• 4^5=1024
  bcz each level can have 4 or 0 child so total may have (1024+1) including root node
