Direction (41–52): What will come in the place of (?) mark in following question?

$5\times \sqrt{?}=735÷3$

The correct answer is 2401.

To find the value that should replace the question mark, let us represent the unknown value by $x$. The given equation is:

$5\times \sqrt{x}=735÷3$

First, simplify the division on the right-hand side of the equation:

$735÷3=245$

Now, substitute this value back into the equation:

$5\times \sqrt{x}=245$

Next, isolate the square root term by dividing both sides of the equation by 5:

$\sqrt{x}=\frac{245}{5}$

$\sqrt{x}=49$

To find the value of $x$, square both sides of the equation:

$x={49}^2$

$x=49\times 49$

$x=2401$

Therefore, the value that comes in place of the question mark is 2401.
