Correct Answer - Option 1 : Thrusday
We have to count odd days from Avni's birthday to Siri's birthday.
Here in June, we have to count from 8th.
So Total remaining days in June = 22 (June is of 30 days)
Odd days are as below :
June = 1
July = 3
August = 3
September = 2
October = 3
November = 2
December = 6 (Till 6th December)
So Total odd days = 1 + 3 + 3 + 2 + 3 + 2 + 6 = 20
Hence 20 odd days means 6 odd days.
So Siri's birthday is 6 days after Avni's birthday, means Friday + 6 = Thrusday.
Hence, Siri's birthday is on Thrusday.
