promised to meet again after 36 days. If today is Saturday, on which day will the friends meet again?Solution
Given: A group of friends met at a club 15 days ago and promise to meet again after 36 days. Today is Saturday it means today is 16 day after they met last time. We have to find the 36th day of the meet again. ⇒  After meet day - The day that have passed ⇒ 36 - 15 =  21 Here, 21 days are left to meet again. ⇒ 21  ÷ 7 = 3 (Odd day 0) It means if today is Saturday so, after 21 days is also a Saturday. Hence, the correct answer is "Saturday".
