Explanation
In the month of April, there are 30 days. It is mentioned that each week has 7 days, and in a month, there are 4 weeks. So, the total number of days in the month can be calculated by adding 7+7+7+7, which is equal to 28. Adding 2 more days to this will give us a total of 30 days, which matches the number of days in April. Therefore, the values hidden behind the question marks are 28 and 30.
