The monthly income of a person is rs 8000. If his income is increased by 20%, then what will be his new monthly income?

Answer

To solve the problem step by step, we will follow these calculations:

### Step 1: Identify the initial monthly income
The initial monthly income of the person is given as Rs. 8000.

### Step 2: Calculate the increase in income
To find the increase in income, we need to calculate 20% of the initial income.

\[ \text{Increase} = 20\% \text{ of } 8000 \]

### Step 3: Convert percentage to decimal
We can convert 20% into a decimal by dividing by 100.

\[ 20\% = \frac{20}{100} = 0.20 \]

### Step 4: Calculate the increase
Now, we can calculate the increase by multiplying the decimal by the initial income.

\[ \text{Increase} = 0.20 \times 8000 \]

### Step 5: Perform the multiplication
Calculating the above gives:

\[ \text{Increase} = 0.20 \times 8000 = 1600 \]

### Step 6: Calculate the new monthly income
To find the new monthly income, we add the increase to the initial income.

\[ \text{New Income} = \text{Initial Income} + \text{Increase} \]

\[ \text{New Income} = 8000 + 1600 \]

### Step 7: Perform the addition
Calculating the above gives:

\[ \text{New Income} = 9600 \]

### Final Answer
The new monthly income after the increase is Rs. 9600.
