Question 1161067

A woman is 5 years older than her husband and 10 times as old as their daughter. In 14 years, the sum of their ages will be 100. How old are the woman, husband, and daughter now?
<pre>Let the daughter's age be D
Then woman's age is: 10D, and husband's is: 10D - 5
We then get: D + 10D + 10D - 5 + 3(14) = 100
21D + 37 = 100
21D = 63
Daughter, or {{{highlight_green(matrix(1,6, D, "=", 63/21, "=", 3, years-old))}}}
You think you can now find the 2 other people's ages?
