The ratio between the total cost of handling (indoor) of 1 letter and the total cost of handling (indoor) of 1 parcel is therefore—
1.2 × 1 : 1.26 × 12 = 1 : 12.6.
The normal unit cost for indoor work is £15 (approximately).
For outdoor work the ratio is 1: 10, and the normal unit cost £22 10s.
The ratio for all indoor and outdoor services is therefore approximately 1: 11.
