Jay is 27/56 times as old as denis. In 9 years, a jay will only be 36/65 times as old as Denis. How old will Denis be 14 years from now?
If Denis's age =D
Jay's age =27/56D
27/56D + 9=36/65(D+9), solve for D
D =56 Years - Denis's age
27/56 * 56 =27 Years - Jay's age
56+14 =70 Years - Denis's age 14 years from now.
