In base 8
137+276=435.. given
as in base 10, it will be 95+195=285
similarly (731+672) in base 8 will be (473 +442 = 915) in base 10 which will be 1623 in base 8.

so
137+276=435;
731+672= 1623

1623....7+6=13 so carry is 1 but instead of 3, 5 is used so increase it by two when adding 7 and 6....again 3+7+1(from carry )=11 carry is 1 but in place of 1.... 3 is used so again increased by 2 on adding 3 and 7....further 1+2 +1(from carry)=4...so it would not be increased....now in second case....2+1=3 so donot increase like in former case....3+7=10..increase it by 2 so we get carry 1 and sum 2 again 7+6+1(from carry)=14..increase it by 2 to get 1623
