Correct Answer - Option 1 : 2
Given:
Number is 6843X9
Calculation:
In the given number 6843X9,
Place value of X = 10X
And, Face value of X = X
As, the square of the place value of X is 200 times its place value
∴ (10X)2 = 200X
⇒ 100X2 = 200X
⇒ X = 2
∴ The value of X is 2
Face value is simply defined as the digit itself within a number.
Place value of a digit should be multiplied by the digit value of the position where it is located.
