The ratio between the ages of nila and arjun is 2:5. After 8 years the ratio of theri ages will be 1:2 . The difference between their present age is
[A] 24 years
[C] 20 years
[B] 28 years
[D] 42 years

• Option A 24 years
  2x+8/5x+8=1/2
  solving this we get x=8
  so the present ages is 2*8:5*8=16:40
  Difference between the ages =40-16=24

• let d ratio of their ages be 2x and 5x respectively .
  now as per ques.
  
  aftr 8 yrs:
  
  2x+8/5x+5 = 1/2
  2(2x+8)=5x+8
  4x+16=5x+8
  
  5x-4x=16-8
  x=8
  
  therefore nila's age= 2*8 = 16 yrs
  arjun's age = 5*8 = 40 yrs
  
  Diff. between their ages is = 40-16 = 24 yrs
