The hexadecimal equivalent of 10 ₁₀ is

(a) 10 ₁₆

(b) 1000 ₁₆

(c) A ₁₆

(d) F ₁₆

Answer:

10 ₁₀ is a decimal number. 

To find the hexadecimal equivalent of a decimal number:

• Repeatedly divide the decimal number by 16 until the quotient becomes less than 16 and record all the remainders. 
• The remainders should be written bottom to upwards to get the hexadecimal equivalent of the decimal number.

Here,

• 10 = A
• 11 = B
• 12 = C
• 13 = D
• 14 = E
• 15 = F

Remainder = 010 = 10  

Given, 10 = A

Therefore, 10 ₁₀ = A ₁₆

So, the correct answer is (c).
