Tamilnadu Samacheer Kalvi 4th Maths Solutions Term 3 Chapter 2 Numbers Ex 2.3

What else could you frame some more questions based on this table?
Answer: Students can frame various questions based on the provided table. For example, some questions could be:
(i) What is the price of 6 kg of boiled rice?
The price of 1 kg of boiled rice is Rs 54. So, for 6 kg, it would be \( 6 \times 54 = \text{Rs } 324 \).
(ii) What is the price of 100 g of red chilly?
The price of 1 kg (1000 g) of red chilly is Rs 100. So, for 100 g, it would be \( \frac{100}{1000} \times 100 = \text{Rs } 10 \).
(iii) What is the price of 250 g of tamarind?
The price of 1 kg (1000 g) of tamarind is Rs 180. So, for 250 g, it would be \( \frac{250}{1000} \times 180 = \text{Rs } 45 \).
(iv) What is the price of 2 kg of wheat?
The price of 1 kg of wheat is Rs 40. So, for 2 kg, it would be \( 2 \times 40 = \text{Rs } 80 \).
(v) What is the sum of the price of 6 kg boiled rice and 1 kg raw rice?
The price of 6 kg boiled rice is \( 6 \times 54 = \text{Rs } 324 \). The price of 1 kg raw rice is Rs 56. The total sum would be \( 324 + 56 = \text{Rs } 380 \). Understanding unit prices helps calculate total costs easily.
In simple words: You can ask questions about how much different amounts of each item would cost. Just multiply the quantity by its price per kilogram to find the total.

🎯 Exam Tip: When framing questions from a table, focus on asking for calculations like total cost for a certain quantity, or comparison between item prices.

Question 1. Frame word problems, using the picture given
Answer: Based on the picture showing 8 pieces of cake and the given cost of one piece, students can frame problems such as:
1. How many pieces of cake are there in the picture?
   There are 8 pieces of cake visible in the picture.
2. Find the total cost of 5 pieces of cake.
   Given that the cost of 1 piece of cake is Rs 25.
   So, the cost of 5 pieces of cake will be \( 5 \times \text{Rs } 25 = \text{Rs } 125 \).
This skill helps in applying mathematical concepts to daily life situations, making math more relevant.
In simple words: Look at the cake picture and the price of one piece. You can ask how many pieces there are, or how much a few pieces would cost.

🎯 Exam Tip: When framing word problems from a picture, always include the key numbers and information presented in the image or its description.

Question 2. Frame word problems, using the picture given:
Answer: Based on the picture showing 8 clocks and the given total cost, students can frame problems such as:
1. What is the total cost of 1 clock?
   Given that the total cost of 8 clocks is Rs 490.
   The cost of 1 clock will be \( \frac{\text{Rs } 490}{8} = \text{Rs } 61.25 \).
2. What is the total cost of 3 clocks?
   Since the cost of 1 clock is Rs 61.25.
   The cost of 3 clocks will be \( 3 \times \text{Rs } 61.25 = \text{Rs } 183.75 \).
Framing problems helps improve understanding of division and multiplication in real-world contexts, building practical math skills.
In simple words: See the clocks and their total price. You can ask for the price of one clock or the price of several clocks.

🎯 Exam Tip: When a total cost for multiple items is given, the first step to finding the cost of several items is usually to calculate the unit cost (cost per single item).
