A father is three times as old as his son After 15 years the father will be twice as old as his sons age at that time Therefore the fathers current age is?
Well, isn't that a lovely puzzle we have here! Let's paint a happy little picture to solve it. If we let the son's current age be "S," then the father's current age would be "3S." After 15 years, the father will be "3S + 15" and the son will be "S + 15." Since the father will be twice as old as the son at that time, we can set up the equation "3S + 15 = 2(S + 15)" and solve for S. Happy solving!

How many years between 15 B.C. and 15 A.D.?
From 15 BC to 0, there is a timespan of 15 years. From 0 to AD 15, there is a timespan of 15 years. 15 + 15 = 30. So, 30 years. ========================================= From the end of 15 BC to the end of 15 AD = 30 years From the end of 15 BC to the beginning of 15 AD = 29 years From the beginning of 15 BC to the end of 15 AD = 31 years From the beginning of 15 BC to the beginning of 15 AD = 30 years 29: There was no year zero. AD1 follows BC1. Measure from same day in each year: From BC 15 to BC 1 there are 14 years (15 to 14 is 1 year etc) From BC 1 to AD 1 there is 1 year. From AD 1 to AD 15 there are 14 years. Total 29 years. Or, using the rule: Sobtract the two years from each other (count BC as negative) and then subtract another 1 if going from BC to AD and you get 15 - (-15) -1 = 29.
