• A. $42$
• B. $48$
• C. $44$
• D. $84$

Answer 1

The correct option is C $44$

The question states that in a 2 digit number, the product of both the digit is 4 times the value of digit in the tens place.

Suppose unit's digit is $y$

$\therefore$ From the given data we have

$4\times y=4\times 4$

$\therefore$ $4y=16$

$\therefore$ $y=4$

$\therefore$ The required number is $44$.
