Below, you can see three complete equations and one incomplete. Based on the three complete ones, can you complete the incomplete one?

5 $ 4 $ 3 $ 9 = 4215
6 $ 9 $ 2 $ 6 = 3816
4 $ 7 $ 3 $ 3 = 1122
7 $ 2 $ 7 $ 4 = ____

• Ans:- 2418
  5439- contain digits 5, 4, 3, 9
  multiply 5 and 9, 5 * 9=45
  place 4 first and 5 last. now we have 4_ _ 5.
  now multiply 4 and 3, 4*3=12, reversing it gives 21.
  then total number is 4215.
  similarly for 7274 we get
  7*4=28, 2_ _ 8 and
  2*7=14, reversing it we get 41.
  therefore number is 2418.
