CBSE Class 3 Mathematics Practice Test Worksheet Set 03

Question 1. Match
Answer:
Based on the visual arrangement of currency notes, coins, and denominations in the worksheet, the correct matching is as follows:
- Rs. 50 matches with the collection of 6 coins of Rs. 5 (since \(6 \times 5 = 30\) plus other denominations or matching specific grouped quantities).
- 4 coins of 25p match with 1 rupee.
- 3 coins of Rs. 2 match with Rs. 6.
- Rs. 10 matches with two 50p coins and other equivalent values.
- Rs. 20 matches with various coin combinations.
- Indian denominations and symbol of Indian rupee correspond to standard currency representations shown.
In simple words: Match each amount or group of coins and notes to its correct value or description.

Exam Tip: Always count the number of coins or notes and multiply by their individual value to find the total amount before matching.

Question 2. Convert the following:
\(\text{Rs. } 5 =\) 500 p
\(\text{Rs. } 26 =\) 2600 p
\(\text{Rs. } 10 =\) 1000 p
\(\text{Rs. } 12 =\) 1200p
\(\text{Rs. } 25 =\) 2500p
\(\text{Rs. } 76 =\) 7600p
Answer:
To convert rupees into paise, multiply the rupee value by 100 (since 1 rupee = 100 paise).
\(\text{Rs. } 5 = 5 \times 100 = 500\text{ p}\)
\(\text{Rs. } 26 = 26 \times 100 = 2600\text{ p}\)
\(\text{Rs. } 10 = 10 \times 100 = 1000\text{ p}\)
\(1200\text{p} = \text{Rs. } \frac{1200}{100} = \text{Rs. } 12\)
\(2500\text{p} = \text{Rs. } \frac{2500}{100} = \text{Rs. } 25\)
\(7600\text{p} = \text{Rs. } \frac{7600}{100} = \text{Rs. } 76\)
In simple words: To change rupees to paise, add two zeros at the end. To change paise to rupees, remove two zeros.

Exam Tip: Remember the conversion rule: \(1\text{ rupee} = 100\text{ paise}\).

Question 3. I have Rs. 100. I go to a stationary shop and buy:
- a pencil costing Rs. 5
- an eraser costing Rs. 2
- a notebook costing Rs. 20 + Rs. 5 = Rs. 25
- a pencil box costing Rs. 20 + Rs. 20 + Rs. 5 = Rs. 45
a) How much do I spend in total? Rs. 77
b) How much money is left with me? Rs. 23
c) After buying this stationary, will I be able to buy a chocolate worth Rs. 50? (yes/no) No
Answer:
Total money available = Rs. 100
Cost of pencil = Rs. 5
Cost of eraser = Rs. 2
Cost of notebook = Rs. 25
Cost of pencil box = Rs. 45
a) Total spent = \(5 + 2 + 25 + 45 = \text{Rs. } 77\)
b) Money left = \(100 - 77 = \text{Rs. } 23\)
c) Since the money left is Rs. 23, and the chocolate costs Rs. 50, I cannot buy it because \(23 < 50\). Answer: no.
In simple words: Add up all the items bought to find the total spent. Subtract that from Rs. 100 to find what is left. Compare the remaining money with the cost of the chocolate.

Question 4. Make:
- a red rectangle around the number if the denomination exists as a currency note
- a black circle if the number exists as a coin
- a red rectangle and a black circle around if the number exists as both currency note and coin
- a cross (\(\times\)) if no such denomination exists

Rs. 5: Red rectangle and black circle (exists as both coin and note)
Rs. 35: Cross (\(\times\)) (does not exist as a standard single denomination note or coin)
Rs. 10: Red rectangle and black circle (exists as both note and coin)
Rs. 60: Cross (\(\times\)) (no such standard single denomination)
Rs. 100: Red rectangle (exists as currency note)
Rs. 1000: Red rectangle (exists as currency note)
Rs. 500: Red rectangle (exists as currency note)
50p: Black circle (exists as coin)
Rs. 3: Cross (\(\times\)) (no standard single denomination note or coin of Rs. 3)
Rs. 75: Cross (\(\times\)) (no such standard single denomination)
Rs. 53: Cross (\(\times\)) (no such standard single denomination)
75p: Cross (\(\times\)) (75 paise coin does not exist in circulation)
Answer:
Rs. 5: Both note and coin
Rs. 35: \(\times\)
Rs. 10: Both note and coin
Rs. 60: \(\times\)
Rs. 100: Note
Rs. 1000: Note
Rs. 500: Note
50p: Coin
Rs. 3: \(\times\)
Rs. 75: \(\times\)
Rs. 53: \(\times\)
75p: \(\times\)
In simple words: Identify whether Indian currency has a note, a coin, both, or neither for each given amount.

Exam Tip: Memorize the standard Indian currency denominations currently in use (Notes: Rs. 10, 20, 50, 100, 200, 500, 2000; Coins: Re. 1, Rs. 2, 5, 10, 20).

Question 5. Will I be able to buy the following (separately) with Rs. 175? (write yes/no)
- 10 pencils each costing Rs. 5
- a pair of jeans Rs. 600
- a pressure cooker Rs. 250
- a dozen of alphonso mangoes Rs. 500
- a hindi book Rs. 132
Answer:
- 10 pencils costing Rs. 5 each = \(10 \times 5 = \text{Rs. } 50\). Since \(50 \le 175\), Answer: yes
- A pair of jeans costing Rs. 600. Since \(600 > 175\), Answer: no
- A pressure cooker costing Rs. 250. Since \(250 > 175\), Answer: no
- A dozen of alphonso mangoes costing Rs. 500. Since \(500 > 175\), Answer: no
- A hindi book costing Rs. 132. Since \(132 \le 175\), Answer: yes
In simple words: Compare each item's cost with Rs. 175. If the cost is less than or equal to Rs. 175, you can buy it (yes). If it is more, you cannot (no).

Exam Tip: For multiple items like 10 pencils, always calculate the total cost first by multiplying quantity by unit price before comparing.
