What will come in place of question mark (?) in the given questions?
`?%of(140-:6)=7`

Options

A. 60
B. 15
C. 25
D. 30

Answer

To solve the equation \( ?\% \text{ of } (140 - 6) = 7 \), we can follow these steps:

### Step 1: Simplify the expression inside the parentheses
First, we need to calculate \( 140 - 6 \):
\[ 140 - 6 = 134 \]

### Step 2: Rewrite the equation
Now we can rewrite the equation using the simplified value:
\[ ? \% \text{ of } 134 = 7 \]

### Step 3: Convert percentage to a decimal
The percentage can be expressed as a fraction:
\[ ? \% = \frac{?}{100} \]
Thus, the equation becomes:
\[ \frac{?}{100} \times 134 = 7 \]

### Step 4: Solve for ?
To isolate \( ? \), we can multiply both sides by 100:
\[ ? \times 134 = 700 \]

Now, divide both sides by 134:
\[ ? = \frac{700}{134} \]

### Step 5: Calculate the value
Now we perform the division:
\[ ? \approx 5.22 \]

### Step 6: Find the nearest whole number
Since the options provided are whole numbers, we can round \( 5.22 \) to the nearest whole number, which is \( 5 \).

### Step 7: Check the options
The options provided were:
1. 60
2. 15
3. 25
4. 30

Since \( 5 \) is not an option, we need to check the calculations again.

Upon reviewing, we realize that we need to multiply \( ? \) by \( 134 \) and then divide by \( 100 \) to find the percentage that equals \( 7 \).

### Final Calculation
To find the correct percentage:
\[ ? = \frac{700}{134} \approx 5.22 \]

### Conclusion
None of the options provided match \( 5.22 \). Thus, we need to check the calculations or the options given.
