Q1
D — The total cost of a robot is found by adding purchase, installation and training costs together. Subtracting the training cost hides part of the expense. It should be total ← buy + fit + train.
Q2
B — A small business is priced out when the robot cost is MORE than its budget. The test should be IF cost > budget THEN, not less than.
Q3
D — This pseudocode FOR loop is closed with NEXT, not ENDFOR. The line should be NEXT year so the yearly repair costs add up.
Q4
B — Each robot costs 40000, so the total for several robots is found by multiplying. It should be cost ← robots * 40000, not adding.
Q5
A — An IF statement must end its condition with THEN. The line should be IF cost > budget THEN.
