• a+c=15
  a-b=2
  b-c=3
  after solve it
  we get a=10,b=8,c=5

• a-b=3
  b-c=2
  ------
  a-c=5
  ------
  sum of the ages of two sons a+c=15
  a-c=5
  a+c=15
  -------
  2a=20
  a=10
  ------
  10+c=15
  c=5.
  b-5=2
  b=7.
  Therefore a=10,b=7,c=5.

• ans: 10
  the difference of age of sons are 3,2. so if the age of elder is 10, the d second son age is 10-3=7,and third ll b 7-2=5. the sum of eldest and one son is 15..so 10+5=15 ..hence proved..lol
