Answers
Given : list of 10 Dates . and month told to Vikram and date told to Muthu
To find : Exact Date of Birth
Solution:
Dates
MAY 15 , 19 , 21
JUNE 17 , 18
JULY 14 19
AUGUST 14 , 15 , 17
Vikram knows month only so Vikram does not know the correct date of birth as each month has more than one date
But Vikram say Muthu also do not know the correct date of birth
hence the Month known to Vikram does not have unique date ( which is only in a particular month like 18th june & 21st May)
hence MAY & JUNE can not be Month
So now Muthu knows that
Month is JULY or AUGUST only ( which was not known to him earlier)
14 Can not be date as then Muthu would not know which month ( July or august)
Hence possible date are 19 JULY , 15 AUGUST & 17 AUGUST
but now Vikram says he also know date of birth
it means month is not august as if it would have been august then Vikram could not know which date
Hence 19 JULY is the DOB
Her birthday on 19 July
