Question

Estimate each of the following products using the general rule $:$

$9258\times 27$

Answer 1

We want to find out the product $9258\times 27$ using general rule

First write $9258$ to the nearest thousand

In $9258$ the hundred digit is $2,$ less than $5$ unchanged the thousand digit and replace the hundred$,$ ten's and unit digit by $0$

Nearest to thousand to $9258$ is $=9000$

In $27$ the unit digit is $7,$ which is greater than $5$ increase the ten's digit by $1$ and replace the unit digit by $0$

Nearest ten's to $27$ is $=30$

Required product $=9000\times 30$

$=2,70,000$

Hence$,$ the product of $9258\times 27$ nearest to thousand is $2,70,000$
