Q. If 8th of the month falls three days after Sunday, what day will be on 17th of that month?
a) Thursday
b) Friday
c) Tuesday
d) Wednesday
Correct Answer: b) Friday
Question from UPPSC Prelims CSAT 2025
Explanation:
Three days after Sunday is Wednesday, so the 8th is a Wednesday.
The 17th is 9 days after the 8th. Since 9 ≡ 2 (mod 7), move 2 days ahead from Wednesday: Wednesday → Thursday → Friday.
Therefore, the 17th is a Friday.
