What value will come in place of the question mark (?) in each of the following questions ?
`6.33-1.32-1.36+1.39-1.23-?=3`

Options

A. `0.81`
B. `0.82`
C. `0.87`
D. `0.86`

Answer

To solve the equation \( 6.33 - 1.32 - 1.36 + 1.39 - 1.23 - ? = 3 \), we will follow these steps:

### Step 1: Rearrange the equation
We can rearrange the equation to isolate the question mark (?):
\[ 6.33 - 1.32 - 1.36 + 1.39 - 1.23 - ? = 3 \]
This can be rewritten as:
\[ 6.33 - 1.32 - 1.36 + 1.39 - 1.23 = 3 + ? \]

### Step 2: Calculate the left side
Now, we will calculate the left side of the equation:
\[ 6.33 - 1.32 = 5.01 \]
\[ 5.01 - 1.36 = 3.65 \]
\[ 3.65 + 1.39 = 5.04 \]
\[ 5.04 - 1.23 = 3.81 \]

### Step 3: Set up the equation
Now we have:
\[ 3.81 = 3 + ? \]

### Step 4: Solve for ?
To find the value of ?, we can subtract 3 from both sides:
\[ ? = 3.81 - 3 \]
\[ ? = 0.81 \]

### Final Answer
Thus, the value that will come in place of the question mark (?) is:
\[ \boxed{0.81} \]
