Five magnifying glasses have been laid out on a table. Let's call them A, B, C, D, and E, with A on the left, B next to it, and so on. The lenses have different magnifications, these being 2x, 4x, 8x, 16x and 32x magnification.

Using the hints below, can you order them, from strongest to weakest magnification?

  • D is four times stronger than E

  • The weakest magnifying glass is not C or E

  • C has 8x magnification

  • A has weaker magnification than E

  • B has stronger magnification than D

  • $\begingroup$ I liked this puzzle. I think I figured it out... but @JonMarkPerry got it before I did, so he deserves the tick. Either way, I found the puzzle quite fun! DVL3 $\color{darkorange}{\bigstar}$ :D $\endgroup$ – Mr Pie Sep 3 '18 at 21:00
  • $\begingroup$ I'm downvoting because 2 of the clues are unnecessary $\endgroup$ – isaacg Sep 4 '18 at 3:33

B, D, C, E, A


Clue 3 tells us C is 8x. Clue 1 now tells us D is 16x and also that E is 4x. Only two magnifying glasses, A and B, now remain, and we can use either that A is therefore 2x from clue 4, or that B is 32x from clue 5.

  • $\begingroup$ Correct, sorry if that was easy $\endgroup$ – Xavier Stanton Sep 2 '18 at 4:15
  • $\begingroup$ nah it was great! clue 2 is redundant btw. $\endgroup$ – JMP Sep 2 '18 at 4:19
  • $\begingroup$ Sorry about that $\endgroup$ – Xavier Stanton Sep 2 '18 at 4:22
  • $\begingroup$ After applying clue 3, clue 1 is already sufficient to place D and E. $\endgroup$ – Peter Taylor Sep 3 '18 at 13:20
  • $\begingroup$ The editing following my previous comment has introduced a false statement. Clue 1 says four times, not eight times. $\endgroup$ – Peter Taylor Sep 3 '18 at 20:15
