Find the one which does not belong to that group ?

  • A.358
  • B.246
  • C.134
  • D.862

Answer: D

In three of the numbers, the first two digits add to the third.

\[ 358: \; 3 + 5 = 8 \quad\checkmark \qquad 246: \; 2 + 4 = 6 \quad\checkmark \]

\[ 134: \; 1 + 3 = 4 \quad\checkmark \qquad 862: \; 8 + 6 = 14 \neq 2 \quad\times \]

So 862 does not belong.
