I am currently 9 times as old as my daughter. Next year, I will be 7 times as old as my daughter. How old is my daughter now?

Your daughter's age now =D

Your age now                     =A

A = 9D..............................(1)

 

Next Year:

A  + 1 =7[D + 1]................(2), solve for A, D

D = 3 year now 

A = 27 years now.

 

3 + 1 = 4 years -daughter's age next year.

4 x 7 = 28 years - your age next year.
