42

The red colored digits should be made '0' as they are before 10s place.

But before you just discard the other digits and replace them with  0s, you need to decide whether you will round up or down.

The 1s place value is 2, which is less than 5. So we have need round down(replace 2 with 0)

So the rounded off value is 40.
