Question

In the given question, select the related number from the given alternatives.
$24$ $:$ $126$ $:$ $:$ $48$ $:$ $?$

• A. $433$
• B. $192$
• C. $240$
• D. $252$

Answer 1

The correct option is D $252$

$24:126=5^2-1:5^3+1$

Similarly,

$48:344=7^2-1:7^3+1$

Alternatively,

$24:126::48:X$

or, $X=\frac{126\times 48}{24}=252$

Hence, D is the correct option.
