Rajiv is 84 weeks and 14 days older than me, whereas Sara is 90 weeks and 12 days older than Rajiv. If Sara was born on a Saturday, on which day of the week was I born?
Sara is 84 + 90 = 174 weeks and 14 + 12 = 26 days older than me. Weeks are in multiples of 7 days. So we can ignore them. We can deal with the 26 days alone. Since 26 = 3 X 7 + 5, the excess days are 5. So we can count the day to Saturday + 5 = Thursday..
