Gross diameter of the rivet hole is 1.5 mm in excess of its normal diameter if it is less than or equal to 25 mm
Gross diameter of the rivet hole is 2.0 mm in excess of its normal diameter if it is greater than 25 mm
The total deduction area for the holes is obtained by the product of the thickness and sum of the diameters of the holes in any chain across the member
All the above.

Here it's given that the "Gross diameter of the river hole is 1.5 mm over its normal diameter if it is greater than 25 mm."

And The correct version should be:

"Gross diameter of the rivet hole is 1.5 mm over its normal diameter if it is 25 mm or less."

For rivet holes:
- If the rivet diameter is 25 mm or less, the gross diameter of the hole is 1.5 mm larger.
- If the rivet diameter is greater than 25 mm, the gross diameter of the hole is 2.0 mm larger.
