Answer 1

The correct option is A 4,40,000 and 4,41,000

(i) Let us round off each number to nearest ten thousands.

489342 rounds off to 490000
48365 rounds off to 50000

Estimates difference
= 490000 – 50000 = 4,40,000

(ii) Let us round off each number to nearest thousands.

489342 rounds off to 489000
48365 rounds off to 48000

Estimated difference
= 489000 – 48000 = 4,41,000
