text: # Mathematical pattern problem 4 / 5 = ?
  
  In an entrance test, Deepika came across a mathematical pattern problem.
  If
  6 / 7 = 2
  3 / 9 = 7
  8 / 2 = 6
  Then
  4 / 5 = ?
  She was able to solve it in less than a minute. Can you?

  The answer is 0.
  As
  6 * 7 = 42 but the answer is written as 2
  3 * 9 = 27 but the answer is written as 7
  8 * 2 = 16 but the answer is written as 6
  If we look at the answers, the second digit has been used in the problem.
  Now, as
  4 * 5 = 20 and the second digit is 0, the answer is 0.
