pallavi doesn't feel she is really a child anymore.ten years ago,her mother was
five times her age.now she is three sevenths of her mothers age,and in five years she will be half her
mother's age
.how old will she be when she is half her mother's age.
a)18 b)20 c)22 d)28

• (M-10)=5*(P-10) AND P=3/7*M
  Solving P=15
  So after 5 yrs P=20

• M be Mother,P be pallavi;before 10yrs, let age of M,p is x,5x;
  aftr 10yrs 3/7(5x+10),x+10;solving those two eq's we get x=5;
  after 5 yrs M age is 5x+10+5=(5*5+10+5)=40;
  given pallavi age is half of her mother agei.e., 40/2=20

• let the age of pallavi be p and mother be m
  then
  5(p-10)= m-10 and 3/7m= p
  so by solving we get p=15
  hence after 5 year she will be 15+5=20 years ans is b
