Answer for screen readers
- Item 1: ₹ 5 left
- Item 2: ₹ 13 left
- Item 3: ₹ 5 left
- Item 4: ₹ 16 left
- Item 5: ₹ 24 left
For the second part:

- How many make Rs 20? 2 coins (₹ 10 each)
- How many make Rs 40? 4 coins (₹ 10 each)
- How many make Rs 60? 6 coins (₹ 10 each)
- How many make Rs 10? 1 coin (₹ 10)
- How many make Rs 12? 1 coin (₹ 10) and 2 coins (₹ 1 each)
Steps to Solve
-
Subtract for each item For each item, subtract the price of the item from the amount given.
- For example,
- Item 1: Amount = ₹ 15, Price = ₹ 10. Calculation: $$ 15 - 10 = 5 $$ So what's left is ₹ 5.
-
Repeat for other items Continue the same subtraction process for the other items:
-
Item 2: Amount = ₹ 20, Price = ₹ 7. Calculation: $$ 20 - 7 = 13 $$ What's left is ₹ 13.
-
Item 3: Amount = ₹ 10, Price = ₹ 5. Calculation: $$ 10 - 5 = 5 $$ What's left is ₹ 5.
-
Item 4: Amount = ₹ 20, Price = ₹ 4. Calculation: $$ 20 - 4 = 16 $$ What's left is ₹ 16.
-
Item 5: Amount = ₹ 30, Price = ₹ 6. Calculation: $$ 30 - 6 = 24 $$ What's left is ₹ 24.
-
-
Count the coins for the second part Determine how many coins are needed to make the specified amounts.
- For example, to make ₹ 30 using given coins, if the coins are ₹ 10 each: Calculation: $$ 30 \div 10 = 3 $$ You need 3 coins of ₹ 10.
- Item 1: ₹ 5 left
- Item 2: ₹ 13 left
- Item 3: ₹ 5 left
- Item 4: ₹ 16 left
- Item 5: ₹ 24 left
For the second part:
- How many make Rs 30? 3 coins (₹ 10 each)
- How many make Rs 20? 2 coins (₹ 10 each)
- How many make Rs 40? 4 coins (₹ 10 each)
- How many make Rs 60? 6 coins (₹ 10 each)
- How many make Rs 10? 1 coin (₹ 10)
- How many make Rs 12? 1 coin (₹ 10) and 2 coins (₹ 1 each)
