Find the one which does not belong to that group ?

  • A.104
  • B.110
  • C.108
  • D.112

Answer: B

Three of the four are multiples of 4.

\[ 104 = 4 \times 26, \quad 108 = 4 \times 27, \quad 112 = 4 \times 28 \]

\[ 110 = 4 \times 27 + 2 \]

So 110 does not belong. The test is the last two digits: 04, 08 and 12 divide by 4, while 10 does not.
