Rounding off using general rule

578\Rightarrow600\ \ and\ \ 161\Rightarrow200578⇒600 and 161⇒200

So, 600\times200\ =\ 1,20,000600×200 = 1,20,000

(b) 5,281\times3,4915,281×3,491

Rounding off using general rule

5,281\Rightarrow5,000\ \ and\ \ 3,491\Rightarrow3,0005,281⇒5,000 and 3,491⇒3,000

So, 5,000\times3,000\ =\ 1,50,00,0005,000×3,000 = 1,50,00,000

(c) 1,291\times5921,291×592

Rounding off using general rule

1,291\Rightarrow1,300\ \ and\ \ 592\Rightarrow6001,291⇒1,300 and 592⇒600

So, 1,300\times600\ =\ 7,80,0001,300×600 = 7,80,000

(d) 9,250\times299,250×29

Rounding off using general rule

9,250\Rightarrow9,000\ \ and\ \ 29\Rightarrow309,250⇒9,000 and 29⇒30

So, 9,000\times30\ =\ 2,70,0009,000×30 = 2,70,000
