Q. Ten years ago, the age of Anand was one third the age of Bala at that time, the present age of Bala is 12 years more than the present age of Anand. Find the present age of Anand?

Option
a) 16
b) 18
c) 20
d) 22

• Let the age of Anand be x years and that of Bala be y years.
  10 years ago,
  means x-10=1/3(y-10) [Ten years ago, the age of Anand was one third the age of Bala]
  y=12+x [The present age of Bala is 12 years more than present age of Anand]
  Solving these two equations by elimination method or substitution method, we get x=16 and y=28

• The first thing to be noted while solving the ages problems is the difference between ages always remains the same.If the diiference at present is 12 years, it is the same even before ten years.
  At that time. Anand was one thirs of the age of Bala, so their ages were 6 and 18 respectively.
  So, present ages were, 16 and 28 respectively.

• If present age of Anand is x
  If present age of Bala is y
  so that
  
  x-10=1/3(y-10)....(1)
  y=x+12................(2)
  so that x=16 Ans
