Hex of decimal 125 – UGC NET Question

Dividing 125 by 16 gives a quotient of 7 and a remainder of 13. In hexadecimal, 13 is represented by D. Therefore, 125 in decimal is written as 7D₁₆. This reflects 7×16 + 13 = 112 + 13 = 125.

Option A:
Option A, 7C₁₆, represents 7×16 + 12 = 124, which is one less than 125. The remainder is too small.

Option B:
Option B is correct because 7×16 = 112 and adding the remainder 13, mapped to D, gives 125. This matches the standard hex conversion process.

Option C:
Option C, 7E₁₆, equals 7×16 + 14 = 126, one more than 125. It overshoots the required value.

Option D:
Option D, 7F₁₆, corresponds to 7×16 + 15 = 127, which is even further from 125.
