The average age of a husband and wife was 23 years when they were married 5 years ago. The average age of the husband, the wife and a child who was born during the interval, is 20 years now.
How old is the child now?
Husband +wife=46....at the time of marriage
Husband +wife=56......present age addition
Husband+wife +child=60...present addition
By solving above equations we get
(H+W)/2=23+5=28 → H+W=56 now H=Husband
(H+W+C)/3=20 → H+W+C=60 now W=Wife
C=60-56=4 yrs old C=Child
A husband and wife have a combined age of 91. If husband is now twice as old as his wife was when he was as old as she is now.
How old are they now?
