Find the approximate value that should replace the question mark (?) in the following equation:
Correct Answer :
243
Solution :
The correct option is 243.
Given Equation:
Step 1: Round off the numbers to their nearest integers to simplify calculation:
80.95 ≈ 81
23.97% ≈ 24%
325.09 ≈ 325
55.96 ≈ 56
7.93 ≈ 8
88.06 ≈ 88
Step 2: Substitute the approximate values into the equation:
Step 3: Solve individual operations using BODMAS/PEMDAS rules:
First, perform the division operation:
56 ÷ 8 = 7
Next, calculate the percentage term:
24% of 325 = (24 / 100) × 325 = 78
Step 4: Substitute these evaluated values back into the equation:
Subtract 85 from both sides of the equation:
Multiply both sides by 81 to solve for ?:
Thus, the approximate value that should replace the question mark is 243.
