Question

Out of the four choices given below, you have to select one that will maintain the relationship on the two sides of the sign ': :' the same if it is substituted for the question mark TSR : FED : : WVU : ?

• A. $CAB$
• B. $MLK$
• C. $PQS$
• D. $IHG$

Answer 1

The correct option is D $IHG$

We can clearly see that each combination of three alphabets are the consecutive alphabets in reverse order.

$RST,DEF,UVW$

Now the one that should replace the question mark should also be of the same kind so the probable answers from the given options are options $B,D$

Now, considering left side of : :, we get

$T,S,R$, which are the ${20}^{th},{19}^{th},{18}^{th}$ letter of alphabets respectively

And,$F,E,D$ are the $6^{th},5^{th},4^{th}$ letter of alphabets respectively

So, $20-6=19-5=18-4=14$

Now, considering right side of : :, we get

$W,V,U$, which are ${23}^{rd},{22}^{nd},{21}^{st}$ letter of alphabets respectively.

And from the left side we know that alphabets that replace question marks will be alphabets corresponding to following numbers,

$23-14=9=I$

$22-14=8=H$

$21-14=7=G$

Hence, the answer is $IHG$ which is option $D$
