Option C

28

Solution :

To find the value that should replace the question mark (?), we can write down the given equation and solve it step-by-step:
13×?×6=472625

First, let's calculate the square of 47:
472=47×47=2209

Next, find the square root of 625:
625=25

Now, substitute these values back into the right side of the equation:
472625=220925=2184

So, the equation simplifies to:
13×?×6=2184

Simplify the left side by multiplying the constants:
13×6=78
Which gives us:
78×?=2184

Solve for (?) by dividing 2184 by 78:
?=218478

Let's perform the division:
?=28

Therefore, the correct option is 28.
