Option 1 : 90

Given:

The number 834.

Concept Used:

(i) Place Value: Place value is the value represented by a digit in a number on the basis of its position in the number.

(ii) Face Value: The Face value of a number is the value of the digit itself.

Calculation:

We know that,

The Face value of 3 in 834 is 3.

The Place value of 3 in 834 is 30.

As per the question,

The Product of the Face value and Place value = 3 × 30

⇒ 90.

∴ The product of the face value and the place value of digit 3 in the number 834 is 90.
