Fill in the blanks and select the CORRECT option.
(i) The difference between the place value and the face value of the digit 9 in 49231 is _____.
(ii) The number 25432 when rounded off to the nearest hundreds gives _____.

Detailed Solution for Test: High Order Thinking Skills - 3 - Question 1

Part (i): The place value of 9 in the number 49231 is 9000 (because it is in the thousands place). The face value of 9 is simply 9. The difference between the place value and face value is 9000 - 9 = 8991.

Part (ii): The number 25432 rounded to the nearest hundreds involves checking the tens place, which is 3. Since the digit in the tens place is less than 5, we round down the hundreds place. Therefore, 25432 becomes 25400 when rounded to the nearest hundreds.

So, the correct answer is Option C: 8991 and 25400.
