The combined age of husband and wife on their 20th wedding anniversary was twice than it was at the time of wedding. If the husband is 3 years older than his wife. How old was he at the time of his marriage?	Pick.
A) 29 years	B) 38.5 years	C) 21.5 years	D) 32 years	E) None of these
Explanation:   Let the ages of husband and wife at the time of their 20th wedding anniversary be X years and Y years respectively and X &gt; Y.   Their combined age = (X + Y) years.   The ages of both husband and wife at the time of wedding will be (X – 20) years and (Y – 20) years respectively.   Their combined age = (X – 20) + (Y – 20)   = (X + Y – 40) Years   By first information, we have   (X + Y) = 2( X + Y – 40)   X + Y = 2X + 2Y - 80   Therefore, X + Y = 80-------A   and by second information, we have   X – Y =3 ----------------------B   Solving A and B, we get X = 41.5 years   Therefore, the age of husband at the time of their 20th wedding anniversary X = 41.5 years   Age at the time of marriage = 41.5 years – 20 years = 21.5 years.   ANSWER IS 21.5 years
