A 15.729kg
B. 25.964kg
C. 26.964kg
D. 26.946kg

Options

A. A
B. C
C. B
D. D

Answer

To find the combined weight of Geetha and her sister, we can follow these steps:

### Step 1: Determine Geetha's Weight
Geetha's weight is given as:
\[ \text{Geetha's weight} = 11.235 \, \text{kg} \]

### Step 2: Calculate Sister's Weight
Her sister weighs 1.4 times Geetha's weight. We can calculate her sister's weight (let's denote it as \( S \)) using the formula:
\[ S = 1.4 \times \text{Geetha's weight} \]
Substituting Geetha's weight:
\[ S = 1.4 \times 11.235 \, \text{kg} \]

### Step 3: Perform the Multiplication
Now, we calculate:
\[ S = 1.4 \times 11.235 = 15.729 \, \text{kg} \]

### Step 4: Calculate Combined Weight
Next, we find the combined weight of Geetha and her sister (let's denote it as \( C \)):
\[ C = \text{Geetha's weight} + \text{Sister's weight} \]
Substituting the values:
\[ C = 11.235 \, \text{kg} + 15.729 \, \text{kg} \]

### Step 5: Perform the Addition
Now, we calculate the combined weight:
\[ C = 11.235 + 15.729 = 26.964 \, \text{kg} \]

### Final Answer
Thus, the combined weight of Geetha and her sister is:
\[ \text{Combined Weight} = 26.964 \, \text{kg} \]

### Conclusion
The correct option is C. 26.964 kg.
