Manish buys Rs 8.75 metro ticket with a Rs 20 note. How much money does he get back ?

Answer

To find out how much money Manish gets back after buying the metro ticket, we can follow these steps:

### Step 1: Identify the total amount given and the cost of the ticket.
- Manish gives a Rs 20 note.
- The cost of the metro ticket is Rs 8.75.

### Step 2: Set up the subtraction to find the change.
- We need to calculate the change by subtracting the cost of the ticket from the amount given.
- The formula for this is:
\[ \text{Change} = \text{Total Amount Given} - \text{Cost of Ticket} \]
In numbers, this is:
\[ \text{Change} = 20 - 8.75 \]

### Step 3: Convert the numbers to decimals for easier subtraction.
- We can express Rs 20 as Rs 20.00 to align the decimal points:
\[ 20.00 - 8.75 \]

### Step 4: Perform the subtraction.
- Align the numbers:
```
20.00
- 8.75
---------
```
- Start subtracting from the right:
- In the hundredths place: 0 - 5 = 5 (we need to borrow)
- In the tenths place: 0 (after borrowing) becomes 10, so 10 - 7 = 3
- In the units place: 0 (after borrowing) becomes 9, so 9 - 8 = 1
- In the tens place: 2 - 0 = 2
- The result of the subtraction is:
\[ 20.00 - 8.75 = 11.25 \]

### Step 5: State the final answer.
- Therefore, Manish gets back Rs 11.25.
