placement of 'per year' in a sentence
In the first sentence, the term ‘per year’ is placed within the sentence and in the second sentence, at the end.
Which pattern is correct and which one is wrong?
The business purchases about 24 tons of hosiery waste as raw material per year from different suppliers located mainly in Dhaka district.
The business purchases about 20 tons of raw materials from different suppliers located mainly in Dhaka district per year.
Solution 1:
The context uses measure units, so I'd combine it as '24 tons per year' (= 24 t/year):
The business purchases about 24 tons per year of hosiery waste as raw material from different suppliers located mainly in Dhaka district.
The less formal version '24 tons of hosiery waste per year' would also be OK unless it wouldn't come into conflict with the expressed here idea of purchasing waste as raw material.
