Siva was born on April 15, 2022. The same year Independence day was celebrated on Monday. On which day was Siva born?

Siva's birth date = April 15, 2022
Independence Day = August 15, 2022 (Given as Monday)

Let's calculate the total number of days between April 15 and August 15, 2022:

* Remaining days in April = $30-15=15$ days
* May = 31 days
* June = 30 days
* July = 31 days
* Days in August up to 15th = 15 days

Total number of days = $15+31+30+31+15=122$ days.
Now, divide the total days by 7 to find the number of odd days:

$$\frac{122}{7}=17\text{ weeks}+3\text{ odd days}$$

Since we are moving backward in time from August 15 to April 15:

$$\text{Day on April 15}=\text{Monday}-3\text{ days}=\text{Friday}$$

Hence, Siva was born on a Friday.
