Question

How many Monday are there in a particular month of a particular year, if the month ends on Wednesday?

• A. $4$
• B. $5$
• C. $3$
• D. Data insufficient

Answer 1

The correct option is D Data insufficient

If Monday falls on ${29}^{th}$ or ${28}^{th}$ there will be $5$ or $4$ Mondays.
We cannot say anything as question haven't told us about the total number of days in a month, as different months have different number of days i.e $28$ days or $30$ days or $31$ days or $29$ days.
Therefore option D is correct.
