Correct Answer - Option 3 : Friday

The logic followed here is:

Given: 11^{th} day of the month is Saturday and the total number of days is 31.

Previously Saturday would have been failing on the date:

11^{th} – 7 = 4^{th}

The day before Saturday is

1. Friday

2. Thursday

3. Wednesday

Friday is 3^{rd} day of the month.

This means next Friday will fail on the dates:

3^{rd} + 7 = 10^{th}

Next

10^{th} + 7 = 17^{th}.

Next

17^{th} + 7 = 24^{th}

Next

24^{th} + 7 = 31^{th}

Thus we can see there are 5 Friday (3, 10, 17, 24, 31).

Hence, the correct answer is **“Friday”.**
