(b) 7000
(c) 7
(d) 70,000

Answer 1

Hint: We start solving the problem by recalling the definition of the face value of a digit as the digit itself presents in a number and it has a property that it does not depend on the position where it is located in the number. We then find the face value of the given digit of the number to get the required answer.

Complete step by step answer:
According to the problem, we are asked to find the face value of 7 in number 3728456.
Let us recall the definition and properties of the face value of a digit in the given number.
We know that the face value of a digit in a number is simply defined as the digit itself present in a number. The face value of a digit remains the same, irrespective of the position where it is located in the number.
So, the face of the digit 7 in the number 3728456 is 7.
 $\therefore$ The correct option for the given problem is (c).

Note:
We should confuse face value with the place value. The place value of a digit in a number is dependent on the positional of the digit in the given number. We should not multiply 7 with 1,00,000 if we are asked to find the face value which is the common mistake done by students. Whereas we multiply 7 with 1,00,000 to find the place value of 7 in the given number.
