   SOLUTION

   • Let the present age of John be x and Martha be y.
   • John is four times as old as Martha.

   • So, x = 4y _(1)

   Five years ago,

   • John’s age = x-5
   • Martha’s age = y-5

   Then, sum of their ages = (x-5)+(y-5) = 50

   • x + y – 10 = 50
   • x + y = 60 _(2)

   Now putting the value of equation (1) in equation (2),we get

   • 4y + y = 60
   • 5y = 60
   • y = 60/5
   • y = 12

   Now putting y=12 in equation (1),we get

   • x = 4 × 12 = 48

   Hence, the present age of John is 48 years and Martha’s age is 12 years.
