Select the  option that is related to the fifth number in the same way as the first number is related to the second number and third number is related to fourth number.

5432 : 2345 :: 6192 : 1269 :: 7835 : ?

3578

Logic here is :

Number on RHS = write digits of LHS number in ascending order .

5432 : 2345

5432 :- digits in ascending order = 2345 

&  6192 : 1269 

6192 :- digits in ascending order = 1269

Similarly ,

 7835 : ?

7835 :- digits in ascending order = 3578

3578 is correct answer .
