8+3+5=16 even. 7+3+4=14 even. 6+4+2=12 even. 7+5+1=13 odd. 8+5+3=16 even. 9+8+1=18 even. 5+3+2=10 even. 751 is answer.

This one is more easy 3+5=8 of 835 3+4=7 of 734 4+2=6 of 642 5+1=6 of 751 This is wrong because we got the result of addition as 6 instead of 7. 5+3=8 of 853 8+1=9 of 981 3+2=5 of 532
