I disagree with you here.
The last digit 89 is the total number of calves after 12 years.
The she-calves with age 0 will be 89 - 55 = 34
Lets revise:
At the end of first year: no of cows: *1* (parent cow) : *First* Fibonacci
Number
At the end of second year: no of cows: *1* (parent cow, now 1
i think for rabbit question answer is 128
as always 2 new rabbits are born from a couple ever alternate month
so at end of 1st month 2
2nd month 4
4rd month 8
6month 16

To post to this group,
@Tushar, after every 2 months, we have twice the additional pairs of rabbits
as before.
So at end of 2nd month 2 pairs added
4th month 4 added
6th month 8 added
8th month 16 added
10th month 32 added
12 th month 64 added
and after 12 months, we have a total of 128 pairs. Which means 256 rabbits.
Pardon.
at end of 2nd month 1 pairs added
4th month 2 added
6th month 4 added
8th month 8 added
10th month 16 added
12 th month 32 added
and after 12 months, we have a total of 128 pairs. Which means 256 rabbits.

As per the analysis from the number of cows produced from the she-calves of
the 1st cow, I get the foll numbers:
1+2+4+7+11+16+22+29+38+48+59+1(MainCow) = 238.
Correct me If am wrong.

Shivnarayan, why should we add all Fibonacci number? Since 1+1 both digits
represent the same cow. I think the last Fibonacci is the answer.
I'm sorry if I'm wrong.

As per the analysis from the
No ans will be sum of all
final fib. number is the no of she-calves of age 0
second last is number is she-calves of age 1

so answer is sum of all
