Anvi's birthday is on Friday 08th June. On what day of the week will be Siri's Birthday in the same year if Siri was born on 06th December of the same year? Correct Answer 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.
