Dear Student,

Explanation-

52---22----30
sum of digits= (5+2=8)-----(2+2=4)------(3+0=3) then arranged second sum of digit placed in first position and first sum of digit placed third position and last sum of digit placed at mid. so arrangement is (437)
similarly
44----31---40
sum of digit= (4+4=8)---(3+1=4)-----(4+0=4) thus arrangement is 448. I hope you got it.

keep learning keep solving
Best wishes
