Question

A city has a population of 72582. Round off the population to the nearest hundred.

• A. 72500
• B. 72600
• C. 73500
• D. 72580

Answer 1

The correct option is B

72600

When we round off a number to the nearest 100, we check the last two digits of the number. If the last two digits form a number less than 50, we round down the number to the nearest lower multiple of 100. If the last two digits form 50 or more than 50, we round up the number to the nearest higher multiple of 100.
72582 has to be rounded off to the nearest hundred. Our options are 72500 or 72600. 82 > 50. Hence 72582 will be rounded off to 72600.
