let pat works for p hours, kate works for p hours and mark works for m hours; such that
p+k+m=162;
also;
p=2k;
p=(1/3)m;
also 2k=(1/3)m;
k=(1/6)m;
m/3+m/6+m=162;
2m+m+6m=162*6;
9m=162*6;
m=18*6=108;

therefore kate works for 1/6(108)=18;

therefore mark charge 108-18=90 hours to work than kate.!!!

Thanks .. I did mistake in equating pats hours with kate and mark.

I did it as p=2k + (1/3)m

2k=(1/3)m;
k=(1/6)m;
i hope it helps...!!!!
