Successive change
Two successive changes of a% and b% give a single net change of a + b + ab/100 per cent. A decrease enters as a negative number.
Example. A price rises 20%, then falls 20%.
Net = 20 − 20 + (20 × −20)/100 = −4%
Second route: 100 → 120 → 96. A loss of 4 ✓
Two routes agreeing is the only confirmation an exam hall gives you.

Unit digit of 1347: base 3, 47 ÷ 4 leaves 3 → third of 3,9,7,1 = 7
Negative clues carry the puzzle
Six friends in a row, all facing north. Clues sorted F / D / X before anyone is placed.

| 2nd | block [FE] | 20 |
| 3rd | C not at an end | 12 |

Syllogism — the two tests
POSSIBILITY test — "is a possibility" holds if true in at least one.
Some A are B. All B are C.
I. All A are C · II. Some A are not C
Neither is definite, but together they are exhaustive: either I or II follows.
Only a few A are B = some are, and some are not. Never drop the second half.
Tap to readRule 1 · Subject–verb agreement
A verb agrees with its subject, never with the noun sitting closest to it.
✗ The register of overdue accounts, all forty of them, were lying on his desk.
✓ … all forty of them, was lying on his desk.
✗ Neither the cashier nor the two tellers has reported the shortfall.
✓ … nor the two tellers have reported the shortfall.
Spotting errors — the four-pass method
(A) Hardly had the meeting begun / (B) when the power failed / (C) than the generator / (D) took over automatically.
Answer (C) — hardly pairs with when; than belongs only with no sooner.
