Question

In the question, there is some relationship according to some rule between the letters and numerals given in each row. Find the rule and then choose the correct alternative from among the four alternatives given under it satisfying the same rule to fill in the vacant places in the third row.

$FJ$	$25$	$16$	$NS$
$LZ$	$25$	$196$	$SX$
$NQ$	$?$	$?$	$WY$

• A. $4,9$
• B. $9,4$
• C. $4,10$
• D. $9,5$

Answer 1

Answer: (A)

$4,9$

We have : $FJ=(F-J{)}^2=(6-10{)}^2=16$
$NS=(N-S{)}^2=(14-19{)}^2=25$;
$LZ=(L-Z{)}^2=(12-26{)}^2=196$;
$SX=(S-X{)}^2=(19-24{)}^2=25$.
So, the missing numbers are :
(i) $WY=(W-Y{)}^2=(23-25{)}^2=(-2{)}^2=4$.
(ii) $NQ=(N-Q{)}^2=(14-17{)}^2=(-3{)}^2=9$.
Hence, option $A$ is the correct answer.
