Find the two digit number, such that the ratio is 7/4 of original number to the number formed by reversing the digits.

• 21 is that number.
  
  Original number = 21
  Reversed number = 12
  
  Ratio = 21:12
  -- > 7:4 of the original number to the number formed by reversing the digits.
  
  Note:
  3*7=21
  3*4=12

• here ratio is 7/4.
  so lets check one by one.
  
  for 1 : 7*1/4*1 = 7/4
  
  for 2 : 7*2/4*2 = 14/8 ,which doesn't satisfy the conditions.
  
  for 3 : 7*3/4*3 = 21/12 ,which is the answer.
