Question

Dee, Eve and Fay each have 22 tokens. They take turns: even means give that many to each of the other two; odd means receive that many from each. Dee spins 4. Eve spins 1. If they end with 15, 30 and 21, what did Fay spin?

Options

  • A. 1
  • B. 2
  • C. 3
  • D. 4

Correct answer

B. 2

Explanation

Everyone starts with 22 tokens. Dee spins 4. Since 4 is even, Dee gives 4 tokens to Eve and 4 tokens to Fay. So Dee loses 8 altogether. New totals: Dee 14, Eve 26, Fay 26 Eve spins 1. Since 1 is odd, Eve receives 1 token from Dee and 1 from Fay. So Eve gains 2 altogether. New totals: Dee 13, Eve 28, Fay 25 Now test Fay's possible spin. To finish on 15, 30 and 21, Fay must lose 4 altogether, while Dee and Eve each gain 2. That happens when Fay spins 2, because 2 is even and she gives 2 to each of the other two. Check: Dee 13 + 2 = 15 Eve 28 + 2 = 30 Fay 25 - 4 = 21 So Fay spun 2.

Question 2 · Multiple choice

Question

A councillor argued that widening the footpath would reduce congestion because people would spread out. Which one of these, if true, most strengthens the argument?

Options

  • A. Widening costs money.
  • B. Wider footpaths elsewhere saw congestion fall.
  • C. Some prefer narrow paths.
  • D. Widening takes time.

Correct answer

B. Wider footpaths elsewhere saw congestion fall.

Explanation

The councillor's idea is that widening the footpath will reduce congestion because people will have more room to spread out. To strengthen this argument, we want evidence that wider footpaths have already reduced congestion somewhere else. If wider footpaths elsewhere saw congestion fall, that strongly supports the claim. It shows that the same kind of change can really improve the flow of people. The other options are weaker: cost does not show whether the idea works, some people preferring narrow paths goes against the argument, and the time needed for building is not evidence about the effect. So the strongest answer is the evidence from places where congestion fell after footpaths were widened.
