$800 is 80% of the original price, so the original is 800 / 0.8 = $1,000. Adding 20% to $800 ($960) is the classic trap: the discount was taken from the larger number.

18 roles in 6 weeks is 3 roles a week, so 45 roles take 45 / 3 = 15 weeks.

The increase is 50 units on a base of 250: 50 / 250 = 0.2, so 20%. 16.7% divides by the new value instead of the starting one.

30% of 120 is 36 who pass; a quarter of 36 is 9 offers.

Candid means open and honest in what you say, which is frank. Secretive is close to its opposite.

An author creates a novel; a composer creates a symphony. The orchestra and the conductor perform it, the instrument plays it.

The text says every analyst uses spreadsheets, not that everyone who uses spreadsheets is an analyst. Maria may or may not be one, so you cannot say.

In one office a second change happened at the same time, so the text cannot separate the two causes. Nothing shows the statement is false either: cannot say.

The gaps grow by 2 each time: +4, +6, +8, +10, so the next gap is +12 and 30 + 12 = 42.

The letters move forward by 2, 3, 4, 5 places, so the next step is 6: O is the 15th letter, and the 21st is U.

The managers who are engineers have safety training, so at least some managers do. Nothing is said about the other managers, or about trained people who are not engineers.

The steps alternate: halve, then multiply by 1.5. 64, 32, 48, 24, 36, and 36 halved is 18.
