If 532=1561028, 641=244630, 785=564035123 then 821=?

Question

If,

Akriti = 631
Levis = 521
Sroti = 521
Aneel = 533
Then,
Sunil =?

Answer 1

Ans is 162824.
Here the logic is..
532=(5*3)(3*2)(2*5)(5*3+3*2+2*5-middle digit of 532 i.e., 3)
So 532=1561028

Same logic is applicable for all
So 821=1628(16+2+8-2(middle digit of 821))
Now the ans is 162824
