Detailed Solution

Rounding off 255 to the upward.
We know that at tens of places we have 5.
Therefore, 255 rounded off upwards is equal to 300.
Similarly,
Rounding off 350 downwards we get 300.
Let’s calculate the product of the two numbers

300 × 300 = 90000

Therefore, the product of the two numbers is 90000.
Hence, option 2 is correct.
