A customer service center had z inbound calls on hold. During the next minute, one-third of those calls were answered but 15 new calls were placed on hold so that 35 callers were then holding.

Quantity A is greater.
Quantity B is greater.
The two quantities are equal.
The relationship cannot be determined from the information given.
After answering one-third, 15 new calls were placed on hold and total number of calls = 35 , i.e.
after answering one- third calls there should be = 20 calls left unanswered,
Therefore it can be written as \((z - \frac{z}{3}) = 20\)
or \(z = 30\)
Check:
one - third of 30 = 10, i.e there are 20 calls left unanswered and 15 calls are added to bring the total of = 35 calls left un-answered
Therefore QTY A > QTY B
