Correct Answer :

Option A

13

Solution :

The correct answer is 13 (Option 1).


Step 1: Calculate the percentage part inside the parentheses.

First, find 35% of 40:

35% of 40=35100×40


=35×40100=1400100=14


Step 2: Multiply the result by 10 inside the parentheses.

Now, multiply 14 by 10:

14×10=140


Step 3: Add 29 to the product under the square root.

Next, add 29 to 140:

140+29=169


Step 4: Take the square root of the final sum.

Finally, find the square root of 169:

169=13


Therefore, the value in place of the question mark (?) is 13.
