Correct Answer: Wednesday

Solution : Given:
15 ^th June→Saturday

Here, the next month with 31 days will be July.
The total number of days from 15 June to 31 days of next month will be –
The remaining number of days in June after 15 June = 15
Number of days in July = 31
Total number of days = 15 + 31 = 46 days
On dividing 46 by 7, the quotient is 6 and the remainder is 4.
Thus, the number of odd days from 15 ^th June to 31 ^st July = 4

Day on 31 ^st July = Saturday + 4 = Wednesday. Hence, the fourth option is correct.
