For the price let the weight column be again used—

1lb. silk @ 12/6= 12/6
4½lb. wor. @  5/-= 22/6
5½lb. twist= 35/-

35/- ÷ 5½ = 6⁄4¼ per lb.

also 5⁄14 of cost is due to silk and 9⁄14 due to worsted.

It is quite evident that this method of procedure yields results of the utmost interest and value to the maker of knitted goods.

Example 32.—Find the counts of 48's cashmere folded with 30's merino. Answer in merino system.

Change 48's cashmere into merino—

48 × 560
= 32's.
840

Using the rule as in (28)—

32 × 30 32 × 30
== 1515⁄31.
32 + 30 62
