Question

Find the odd term out.

• A. $L{J}_1$
• B. $R{F}_7$
• C. $Z{H}_9$
• D. $X{B}_{11}$

Answer 1

The correct option is B $R{F}_7$

$L\to 12,J\to 10$

Difference = $12-10=2$

$\Rightarrow$ $\frac{2}{2}=1$
Similarly,

$Z$ $\to 26;H\to 8$ Difference = $26-8=18$

$\Rightarrow$ $\frac{18}{2}=9$

$X$ $\to 24;B\to 2$ Difference = $24-2=22$

$\Rightarrow$ $\frac{22}{2}=11$

But for option B:

$R$ $\to 18;F\to 6$ Difference = $18-6=12$

$\Rightarrow$ $\frac{12}{2}=6$

Hence option B is odd one out.
