Question 659146

Mira is twelve years older than her brother Carlo. Four years from now, Carlo will be two – thirds as old as Mira will be four years from now. How old are they now?

PLease help me solve this.


Let Carlo's age be C
Then Mira's is C + 12


{{{C + 4 = (2/3)(C + 12 + 4)}}}


{{{C + 4 = 2(C + 16)/3}}}


{{{C + 4 = (2C + 32)/3}}}


3(C + 4) = 2C + 32 ----- Cross-multiplying


3C + 12 = 2C + 32 


3C - 2C = 32 - 12


C, or Carlos' current age = {{{highlight_green(20)}}}


Mira is currently 20 + 12, or {{{highlight_green(32)}}} years-old


Do the check to see if it makes sense!!
