Question

In the given question, select the related number from the given alternatives.
$19$ $:$ $37$ $:$ $:$ $26$ $:$ $?$

• A. $52$
• B. $51$
• C. $46$
• D. $43$

Answer 1

Answer: (B)

$51$

Taking LHS,

We can see that the relation between the two numbers of LHS is second number is 1 less than the twice of first number i.e.

$\Rightarrow (2\times 19)-1=38-1=37$

Applying the same relation to the RHS ,

$\Rightarrow$ $?=(2\times 26)-1=52-1=51$

Hence the correct answer is option $B$
