Best practice
Ensure that the noun or pronoun following "the sum of which" agrees in number with the sum being referred to.
Common error
A common error is using a singular verb after "the sum of which" when referring to a plural subject. Always ensure the verb agrees with the actual sum being described, even if the phrase itself seems singular. Instead of "The measurements were taken, the sum of which was," use "The measurements were taken, the sum of which were."
