Answer» Correct Answer - Option 3 : 1623 Explanation: If we try adding the numbers directly (i.e. considering decimal) Since 7+ 6 =13 and the given answer 435 has 5 in the one’s place, therefore, the numbers are in base 8; because 13 will correspond to 15 (7 + 8) in the base 8 system. Now converting 731 and 672 in decimal (7 × 8^2) + (3 × 8^1) + (1 × 8^0) = 473 (6 × 8^2) + (7 × 8^1) + (2 × 8^0) = 442 Adding 473 + 442 = 915 Converting 915 into base 8 = 1623

Answer» Correct Answer - Option 3 : 1623

Explanation:

If we try adding the numbers directly (i.e. considering decimal)

Since 7+ 6 =13 and the given answer 435 has 5 in the one’s place, therefore, the numbers are in base 8;

because 13 will correspond to 15 (7 + 8) in the base 8 system.

Now converting 731 and 672 in decimal

(7 × 8^2) + (3 × 8^1) + (1 × 8^0) = 473

(6 × 8^2) + (7 × 8^1) + (2 × 8^0) = 442

Adding 473 + 442 = 915

Converting 915 into base 8 = 1623
