Some accountants calculate with simple adding machines, and some use complex computers. One can perform more calculations in less time with a computer than with an adding machine. Therefore, assuming the costs of using the two types of machines are equal, an accountant who uses a computer generally can earn more per hour than an accountant who uses an adding machine.

Which one of the following is an assumption that would make the conclusion in the passage a logical one?

(A) More accountants use computers than use adding machines.
(B) The more hours an accountant spends on the job, the more money he or she will earn.
(C) The more calculations an accountant performs, the more money he or she will earn.
(D) An accountant who uses an adding machine can charge a higher hourly rate than one who uses a computer.
(E) In general, accountants vary in terms of the number of calculations they make and the amount of money they earn.

I have a doubt for this question.

The Conclusion states - "Therefore, assuming the costs of using the two types of machines are equal, an accountant who uses a computer generally can earn more per hour than an accountant who uses an adding machine"

The conclusion talks about "per hour" rate whereas option C supports overall income.
What if the accountant with adding machine has higher per-hour rate but works less hours and accountant with computer puts in more no. of hours then earnings of accountant with computer has more overall income but still per hour rate is low.

The conclusion of the argument is "An accountant who uses a computer can earn more per hour than an accountant who uses an adding machine."
We are given:
1. That computer performs more calculations than do adding machine.
2. Cost of operating is same for both computer and adding machine.
If the cost is same then how can an accountant earn more performing the same task that is
calculating using a computer.

Answer : if the accountant is paid as per the number of calculations he/she performs.
