If 10112 + x7 = 2510, solve for X..... Question 14309

If 1011₂ + x₇ = 25₁₀, solve for X.

20₇

Correct answer is A

1011₂ + x₇ = 25₁₀ = 1011₂ = 1 x 2³ + 0 x 2² + 1 x 2¹ + 1 x 2^o

= 8 + 0 + 2 + 1

= 11₁₀

x₇ = 25₁₀ - 11₁₀

= 14₁₀

\(\begin{array}{c|c}
7 & 14 \\ 7 & 2 R 0 \\ & 0 R 2
\end{array}\)

X = 20₇
