Question 971847
Let mandy and sandy's present ages be m and s respectively.
So,as per ques,
{{{m/s=2/5}}}
=>{{{ s=5m/2}}}    -(i)
Also given,after 8 years,
{{{(m+8)/(s+8) = 1/2}}}
=>{{{2m+16=s+8}}}
=> {{{2m+8=s}}}
=> {{{2m+8=5m/2}}}   using eqn. (i)
=> {{{m=16}}}
So,
{{{s=5m/2=40}}}
So mandy and sandy's present ages are 16 years and 40 years respectively.
and the difference in their ages is 24 years.
So, Caitlin is right.
