Question

Find the product of 235 and 321 after rounding off them to the nearest hundreds.

• A. 40000
• B. 50000
• C. 60000
• D. 80000

Answer 1

The correct option is C 60000

To round off a number to the nearest hundreds, if the tens digit is less than 5, then hundreds digit will remain same and digits to the right of hundreds digit will be replaced by 0.

In 235, tens digit is 3 which is less than 5.
So, 235 is rounded off to 200.

In 321, tens digit is 2 which is less than 5.
So, 321 is rounded off to 300.

200 $\times$ 300 = 60000

Hence, product of 235 and 321 after rounding off them to the nearest hundreds is 60000.
