Question

Four of the following five are alike in a certain way and so form a group. Which is the one that does not belong to the group?

• A. LBT
• B. SPA
• C. IJF
• D. PID
• E. BMS

Answer 1

The correct option is D PID

$L\stackrel{+3}{\to }B\stackrel{-1}{\to }T$
$S\stackrel{+3}{\to }P\stackrel{-1}{\to }A$
$I\stackrel{+3}{\to }J\stackrel{-1}{\to }F$
$P\stackrel{+2}{\to }I\stackrel{-1}{\to }D$
$B\stackrel{+3}{\to }M\stackrel{-1}{\to }S$
So the term PID does not follow the pattern.
