Best answer 30 votes 30 votes Answer. C. $(137)_{8} + (276)_{8} = (435)_{8}$ So basically the number are given in Octal base. Similarly, addition of $731,672$ gives $1623$ in octal. shree answered Oct 22, 2014 • edited Jun 21, 2021 by Lakshman Bhaiya shree comment Share Follow See all 3 Comments See all 3 3 Comments reply Peeyush Pandey commented Dec 15, 2018 reply Follow Share assume base is x then convert numbers in given equation to decimal then find the value of x x^2+3x+7 + 2x^2+7x+6 = 4x^2+3x+5 x=8,-1 base cannot be -1 so x=8 5 votes 5 votes toxicdesire commented Nov 28, 2019 reply Follow Share Why not (A)? - probably because "How much is..." is asked, which signifies quantity, which means the individual terms are supposed to be treated as numbers. If asked as "What is ..." then the question will become ambiguous and option (A) will be equally rightful candidate for the correct option, since the question can be interpreted as an encoding scheme. 5 votes 5 votes ankit3009 commented Jan 22, 2021 reply Follow Share Thanks Sir ji :) 0 votes 0 votes Please log in or register to add a comment.
