Through the table, we can see that Muniya ate a banana on 05/09/05.
As, the 9th month is September, so we can say that she started walking on 05 September, 2005.
Muniya started crawling on 20/11/05.
As, the 11th month is November, so we can say that she started walking on 20 November, 2005.
Number of days after eating a banana did Muniya start crawling
= (30 - 5) days in September + 31 days in October + 20 days in November
= 25 + 31 + 20
= 76 days
