Estimate the sum $579+7994$ by estimating the numbers to its nearest hundreds.

• A. $8600$
• B. $8573$
• C. $7500$
• D. $1200$

Answer 1

Answer: (A)

$8600$

$\Rightarrow$ $579+7994=8573$

$\Rightarrow$ In number $8573$, its tens digit is 7, which is greater than 5.

$\Rightarrow$ So, we increase the digits at hundreds place by 1 and replace each one of the digits at tens and ones place by 0 to round off the given number to nearest to 100.

$\therefore$ The number nearest to 100 is $8600.$
