How can we find the error and absolute percentage error resulting from the rounding of 7412 to 7400.

Thanks

The Error is defined as the difference between the estimated value and true value.
The percentage error is found by comparing the error with the true value and expressing this as a percentage.

Therefore for your question are
Error=estimated value-true value=7400-7412=-12

and Absolute percentage error
