Question

clue choose the correct answer:
a]10 b]12 c]16 d]18

Answer 1

3 since no of lettersind word multiplied by 2 minus 1 gives d result

Answer 2

WAX should be coded as '8'.

You're counting how many times the letters in the words come to a point....

DEAR has 7 distinct points, i.e. the E has 3 points, the A has 2, the R has 2, and the D is a closed loop (therefore, no points)

BEARS has 9 - B (0) + E (3) + A (2) + R (2) + S (2) = 9

so, WAX = W (2) + A (2) + X (4) = 8 distinct points....

Answer 3

DEAR 4 letters..........4 * 2 - 1 = 7
BEARS 5 letters.........5 * 2 - 1 = 9
WAX 3 letters.............3 * 2 - 1 = 5
Therefore the code should be 5

Answer 4

I would say 5
