Question 636600
let the three no's be a,b,c
given third no is three times the first no
so c=3a
and second no is 6 times less than the first no.
so b=a-6
also given that a+b+c=111
now a+a-6+3a=111
    5a-6=111
    5a=111+6
     5a=117
      a=117/5
     a=23.4
    ----------
    b=a-6
     =23.4-6
    b=17.4
   ------------
    c=3a
     =3x23.4
    c=70.2
-----------------
to check the answer a+b+c=111
                   23.4+17.4+70.2=111
                   111=111
           hence the answer.......
