One grand father has 3 grand children two of the age difference is 3.Eldest child age is 3 times the youngest childs age and the eldest child age is two year more than the sum of other two children. Find what is the age of the elders child?
a)18 b)22 c)30 d)10

• Let the age of elder son is E,Middle Son is M,Younger son is Y
  So M-Y=3
  E=3Y
  E=2+(Y+M)
  After solving this equation
  E=15

• A=3C
  A-B=3 OR B-C=3 OR A-C=3
  A=2(B+C)
  IF A=18 THEN C=6
  18=2(B+6)
  B=3
  THUS C-B IS SATISFIED
  SO ANS IS 18

• A=3C
  B-C=3
  A=2+(B+C)
  IF A=18,C=6
  B=9
  SO,B-C is satisfied
  so ans is 18

• let x,,y,z
  x=3y
  x=2+z
  so now x-y=3
  x-x/3=3
  x=9/2 it is multiple of 22 so it should be answer u can take diff of any two and put the conditions u get the answer
