Look at this pair

   42                         24                                                 ( digits of 42 are interchanged i.e =24)

x 48                       x 84                                                 (digits of 48 are interchanged i.e = 84)

--------                   ----------

 2016                      2016

 

When the digit of multiplicand and multiplier are interchanged then also the result is same.

How many such pair can you find?
