Worked Example

Step-by-Step

Let's say you have 4 ten-rupee notes and 1 one-rupee coin. How much money do you have in total?

Step 1: Count the value of the ten-rupee notes. Each note is 10 rupees.

Step 2: You have 4 notes, so 4 x 10 rupees = 40 rupees.

Step 3: Now, add the value of the one-rupee coin. The coin is 1 rupee.

Step 4: Total money = 40 rupees + 1 rupee.

Step 5: 40 + 1 = 41 rupees.

Answer: You have 41 rupees in total.
