Samacheer Kalvi Class 4 Maths Solutions Term 3 Chapter 5 Money Exercise 5.2

I. Add the Following Rupees (Without Conversion)

Question 1. Add Rs 38.40 and Rs 41.25.
Answer: To find the total, we need to add Rs 38.40 and Rs 41.25.
\( \text{Rs } 38.40 + \text{Rs } 41.25 = \text{Rs } 79.65 \)
So, the sum of Rs 38.40 and Rs 41.25 is Rs 79.65. When adding money, it's like combining two separate piles of cash and coins.
In simple words: To get the total money, we add the two amounts together. The answer shows how much money there is in total.

🎯 Exam Tip: Always align the decimal points when adding or subtracting amounts of money to prevent calculation errors.

Question 2. Add Rs 19.27 and Rs 10.31.
Answer: To find the sum, we need to add Rs 19.27 and Rs 10.31.
\( \text{Rs } 19.27 + \text{Rs } 10.31 = \text{Rs } 29.58 \)
Thus, the total amount when adding these two sums is Rs 29.58. Make sure to add the paise (cents) first, then the rupees.
In simple words: When you add Rs 19.27 and Rs 10.31, you get a total of Rs 29.58.

🎯 Exam Tip: Double-check your addition for each column, especially when dealing with decimal numbers, to ensure accuracy.

Question 3. Add Rs 28.50, Rs 20.14 and Rs 41.32.
Answer: To find the total, we need to add Rs 28.50, Rs 20.14 and Rs 41.32.
\( \text{Rs } 28.50 + \text{Rs } 20.14 + \text{Rs } 41.32 = \text{Rs } 89.96 \)
The sum of these three amounts is Rs 89.96. Adding multiple amounts works the same way as adding two, just line up the decimal points.
In simple words: Adding all three amounts of money together gives a total of Rs 89.96.

🎯 Exam Tip: When adding more than two numbers, you can add them two at a time or sum all columns vertically, starting from the rightmost digit.

Question 4. Add Rs 34.20, Rs 13.18 and Rs 12.11.
Answer: To find the total sum, we need to add Rs 34.20, Rs 13.18 and Rs 12.11.
\( \text{Rs } 34.20 + \text{Rs } 13.18 + \text{Rs } 12.11 = \text{Rs } 59.49 \)
The total of these three amounts is Rs 59.49. Each amount adds to the final total, just like counting your money.
In simple words: If you add Rs 34.20, Rs 13.18, and Rs 12.11, the total comes out to be Rs 59.49.

🎯 Exam Tip: Always write down the units (like 'Rs') correctly with your answer, as it shows what the number represents.

II. Add the Following Rupees (With Conversion)

Question 1. Add Rs 19.56 and Rs 23.64.
Answer: To find the sum, we need to add Rs 19.56 and Rs 23.64.
\( \text{Rs } 19.56 + \text{Rs } 23.64 = \text{Rs } 43.20 \)
The sum of Rs 19.56 and Rs 23.64 is Rs 43.20. Sometimes, when adding paise, you might get more than 100 paise, which then converts into additional rupees.
In simple words: When you add Rs 19.56 and Rs 23.64, you get a total of Rs 43.20.

🎯 Exam Tip: Pay close attention to carrying over numbers from the paise column to the rupees column if the sum of paise is 100 or more.

Question 2. Add Rs 64.75 and Rs 36.25.
Answer: To find the total, we need to add Rs 64.75 and Rs 36.25.
\( \text{Rs } 64.75 + \text{Rs } 36.25 = \text{Rs } 101.00 \)
The total amount is Rs 101.00. Adding these specific amounts results in a whole number of rupees, meaning the paise add up perfectly to make another rupee.
In simple words: Adding Rs 64.75 and Rs 36.25 gives you a total of Rs 101.00.

🎯 Exam Tip: Remember that 100 paise equals 1 rupee. This conversion is important when the sum of paise goes over 99.

Question 3. Add Rs 28.37, Rs 18.43 and Rs 17.65.
Answer: To find the total sum, we need to add Rs 28.37, Rs 18.43 and Rs 17.65.
\( \text{Rs } 28.37 + \text{Rs } 18.43 + \text{Rs } 17.65 = \text{Rs } 64.45 \)
The total sum is Rs 64.45. Adding three decimal numbers requires careful alignment and carrying over when needed.
In simple words: If you add Rs 28.37, Rs 18.43, and Rs 17.65 together, you will get a total of Rs 64.45.

🎯 Exam Tip: When adding multiple decimal numbers, it's a good practice to sum the rightmost column first and carry over any tens to the next column.

Question 4. Rs 64.15 + Rs 38.27
Answer: To find the total, we add the amounts shown in the provided solution.
\( \text{Rs } 64.15 + \text{Rs } 38.27 + \text{Rs } 41.18 = \text{Rs } 143.60 \)
The total amount when adding these three values is Rs 143.60. This type of calculation is very common in everyday shopping and budgeting.
In simple words: When you add Rs 64.15, Rs 38.27, and Rs 41.18, the final total is Rs 143.60.

🎯 Exam Tip: Always recheck your addition, especially if it involves carrying over multiple times, to ensure your final sum is correct.

III.

Question 1. Elaovan bought a bat for Rs 105.15 and a ball for Rs 24. How much money did he spend in all?
Answer:Money spent on bat \( = \text{Rs } 105.15 \) Money spent on ball \( = \text{Rs } 24.00 \) Total money spent \( = \text{Rs } 105.15 + \text{Rs } 24.00 = \text{Rs } 129.15 \) Elaovan spent a total of Rs 129.15. This calculation helps us know the combined cost of two items.
In simple words: Elaovan spent Rs 105.15 on a bat and Rs 24 on a ball. So, he spent Rs 129.15 in total.

🎯 Exam Tip: When a problem asks "how much in all" or "total amount," it usually means you need to add the given values together.

Question 2. Sadham went to vegetable shop and bought 1 kg of brinjal for Rs 28.50, 1 kg of ladies finger for Rs 10.50, 1 kg of pumpkin for Rs 11.50. Find the total amount he spent in all.
Answer:Cost of brinjal \( = \text{Rs } 28.50 \) Cost of ladies finger \( = \text{Rs } 10.50 \) Cost of pumpkin \( = \text{Rs } 11.50 \) Total amount spent \( = \text{Rs } 28.50 + \text{Rs } 10.50 + \text{Rs } 11.50 = \text{Rs } 50.50 \) Sadham spent a total of Rs 50.50 at the vegetable shop. Adding up the costs of all items helps in managing a budget for shopping.
In simple words: Sadham bought three vegetables. To find out how much money he spent altogether, we add the price of each vegetable. The total is Rs 50.50.

🎯 Exam Tip: Break down word problems into individual items and their costs before performing the final calculation.

Question 3. Kanmani bought pad and pen for her daughter at the cost of Rs 65.50 and Rs 48.75. How much money did she pay for the things?
Answer:Cost of pad \( = \text{Rs } 65.50 \) Cost of pen \( = \text{Rs } 48.75 \) Total money paid \( = \text{Rs } 65.50 + \text{Rs } 48.75 = \text{Rs } 114.25 \) Kanmani paid a total of Rs 114.25 for the pad and pen. This calculation helps in knowing the combined expense for her purchase.
In simple words: Kanmani bought a pad for Rs 65.50 and a pen for Rs 48.75. Adding these prices tells us she paid Rs 114.25 in total.

🎯 Exam Tip: Always clearly state what each value represents (e.g., "Cost of pad") before doing the calculation in a word problem.

Question 4. Ramya bought Vegetable rice, Idly and Dosai for Rs 74.50, Rs 28.50 and Rs 60.50. Find the total amount he spent in all.
Answer:Cost of Vegetable rice \( = \text{Rs } 74.50 \) Cost of Idly \( = \text{Rs } 28.50 \) Cost of Dosai \( = \text{Rs } 60.50 \) Total amount spent \( = \text{Rs } 74.50 + \text{Rs } 28.50 + \text{Rs } 60.50 = \text{Rs } 163.50 \) Ramya spent a total of Rs 163.50 for all the food items. This calculation gives the total sum of all her food purchases.
In simple words: Ramya bought three food items. We add their prices: Rs 74.50, Rs 28.50, and Rs 60.50. The total money spent is Rs 163.50.

🎯 Exam Tip: When dealing with multiple items, list each item's cost clearly before summing them up to make the solution easy to follow.
