Question

Estimate the following product using general rule: $578\times 161$.

Answer 1

Estimate the given product:

Given product is $578\times 161$

Rounding off using general rule, we get,

$578$$\Rightarrow$$600$ and $161$$\Rightarrow$$200$

$\therefore$ Estimated value $=$$600$$\times$$200$$=$$1,20,000$

Hence the estimated value is $1,20,000$.
