Five years ago, Beth’s age was three times that of Amy. Ten years ago, Beth’s age was one half that of Chelsea. If C represents Chelsea’s current age, which of the following represents Amy’s current age?
A. C-10 /3
B. 5/3C-10
C. C/6 +5
D. C – 12/5
E. C/5 + 7

• Option :C
  A represents Beth's present age.
  B represents Amy's present age
  C represents Chelsea's present age.
  (A-5)=3(B-5)
  (A-10)=1/2(C-10)
  =>B=(C/6)+5

• Let Amy's current age= A; Beth's=B; Chelsea's=C
  Given,
  B-5 = 3*(A-5)
  => B=3A-10 -- equation [1]
  
  Also given,
  B-10 = 1/2 * (C-10)
  => B=C/2 +5 -- equation [2]
  
  From equation [1] & [2],
  3A-10= C/2 +5
  => A= C/6 +5
