Renu spends `4/5` of her income on household expenses. Her monthly income is Rs 30000. How much does she save every month?

Options

A. Rs 4000
B. Rs 5000
C. Rs 6000
D. Rs 7000

Answer

To find out how much Renu saves every month, we can follow these steps:

### Step 1: Calculate Renu's monthly expenses
Renu spends \( \frac{4}{5} \) of her income on household expenses. Her total monthly income is Rs 30,000.

To find her expenses, we calculate:
\[ \text{Expenses} = \frac{4}{5} \times \text{Income} \]
Substituting the income:
\[ \text{Expenses} = \frac{4}{5} \times 30000 \]

### Step 2: Perform the multiplication
Now, we perform the multiplication:
\[ \text{Expenses} = \frac{4 \times 30000}{5} = \frac{120000}{5} = 24000 \]
So, Renu spends Rs 24,000 on household expenses.

### Step 3: Calculate Renu's savings
To find out how much Renu saves, we subtract her expenses from her total income:
\[ \text{Savings} = \text{Income} - \text{Expenses} \]
Substituting the values:
\[ \text{Savings} = 30000 - 24000 \]

### Step 4: Perform the subtraction
Now, we perform the subtraction:
\[ \text{Savings} = 6000 \]
Thus, Renu saves Rs 6,000 every month.

### Final Answer
Renu saves Rs 6,000 every month.
