Correct Answer :

Option C

61

Solution :

The correct option is 61.

To find the value that comes in place of the question mark (?), let the unknown value be represented by x.

The given equation is:

((3×12)÷18+1)+84=148-x


Step 1: Simplify the innermost bracket

3×12=36

Substitute this back into the equation:

(36÷18+1)+84=148-x


Step 2: Perform division inside the bracket

36÷18=2

Substitute this back into the equation:

(2+1)+84=148-x


Step 3: Complete the evaluation inside the outer bracket

2+1=3

Now the equation becomes:

3+84=148-x


Step 4: Add the numbers on the left-hand side

87=148-x


Step 5: Solve for x

x=148-87

x=61

Thus, the value in place of the question mark (?) is 61.
