The age of the two friends were in the ration of 2:3. If the sum of their ages is 55. Then after how many years their ratio will become 4:5?
a) 11 b) 33 c) 22 d) 44

• Here the 2+3 = 5
  now 55/5 = 11
  so, 11*2 = 22 and 11*3 = 33
  now Ratio 4:5
  so, 4*11 = 44 and 5*11 = 55
  age diff. 44-22 = 22
  55-33 = 22
  so, Ans is 22

• the ages of frnds are 22 and 33..
  so (22+x)/(33+x)=4/5
  solve this and ans will be 22.

• 22
  
  2x+3x=55
  5x=55
  x=11
  
  22+y/33+y=4/4
  y=22

• 2x+3x=55
  x=11
  22,33
  22+t/33+t=4/5
  110+5t=132+4t
  t=22
  thus after 22 years their age will be in the ratio 4:5
