Correct Answer :

Option C

2

Solution :

The correct answer is 2.

To find the value that should replace the question mark (?), we begin with the given equation:
180 × 18 × 2 60 × 12 - 1 = ? 3

Step 1: Simplify the fractional part of the equation.
Let us evaluate the expression:
180 × 18 × 2 60 × 12
We can simplify the expression by canceling common factors between the numerator and the denominator:
First, divide 180 by 60:
180 60 = 3
Now, the fraction becomes:
3 × 18 × 2 12
Next, multiply 18 by 2 in the numerator:
18 × 2 = 36
This simplifies the fraction to:
3 × 36 12
Now, divide 36 by 12:
36 12 = 3
Finally, multiply the remaining numbers:
3 × 3 = 9

Step 2: Substitute the simplified fraction value back into the original equation.
Substituting 9 for the fractional term gives:
9 - 1 = ? 3
8 = ? 3

Step 3: Solve for the question mark (?).
To find the value of ?, we take the cube root of both sides:
? = 8 3
Since 23=8, we find:
? = 2
