5+3+2 = 151022

9+2+4 = 183652

8+6+3 = 482466

5+4+5 = 202541

7+2+5 = .............................

5+3+2 = 151022

Here 5*3 = 15 And 5*2 = 10

9+2+4 = 183652

Here 9*2 = 18 And 9*4 = 36

8+6+3 = 482466

8*6 = 48 And 8*3 = 24

5+4+5 = 202541

5*4 = 20 And 5*5 = 25

Now

7+2+5 will be

7*2 and 7*5 = 1435

Now See Carefully The Last Two Digits Pattern

If We Add First Two Numbers

Like First Case

15+10 = 25

And Subtract Middle Number Of LHS From Sum We Get Last Number

15+10-3 = 22

18+36-2 = 52

48+24-6 = 66

20+25-4 = 41

Now Last Case

14+35-2 = 47

So Number = 143547
