Estimate the following products by rounding off each of its factors nearest to its greatest place:
(i) \( 578 \times 161 \)
Given: \( 578 \times 161 \)
To do: Estimate by rounding off each of its factors nearest to its greatest place
Solution:
\( 578 \times 161 \)
Rounding off by general rule,
578 rounds off to 600
161 rounds off to 200,
Required product = \( 600 \times 200\)
= 120000
