Question 659148

One – fifth of a certain lawyer’s age 8 years ago equals one – ninth of his age 24 years hence. How old is he now?

How can I solve for this?


Let his current age be C
Then we can say that: {{{(1/5)(C - 8) = (1/9)(C + 24)}}}, with hence meaning from now
{{{(C - 8)/5 = (C + 24)/9}}}
{{{9(C - 8) = 5(C + 24)}}} ----- Cross-multiplying 


9C - 72 = 5C + 120


9C - 5C = 120 + 72


4C = 192


C, or his current age = {{{192/4}}}, or {{{highlight_green(48)}}}


You should be able to do the check!!
