A) 6 B) 60
C) 64 D) 10
 
Answer & Explanation Answer: B) 60

Explanation:

We know that,

● The face value of a digit for any place in the given number is the value of the digit itself

● Place value of a digit = (face value of the digit) × (value of the place).

 

Hence, the place value of 6 in 64 = 6 x 10 = 60.
