Practice lining up the digits properly, especially when dealing with different numbers of decimal places, to avoid common errors.

Question 2. Cost of a pen from shop A is Rs. 7.50 and from shop B is Rs. 5.50. What is the difference between the cost from two shops?
Answer:
Cost of pen from Shop A \( = \) Rs. 7.50
Cost of pen from Shop B \( = \) Rs. 5.50
Difference in cost \( = \) Rs. 7.50 - Rs. 5.50
\( = \) Rs. 2.00
The calculation shows a straightforward subtraction. Finding the difference tells us how much more expensive one item is compared to another.
In simple words: The pen costs Rs. 7.50 at shop A and Rs. 5.50 at shop B. To find how much cheaper one is, subtract the smaller price from the bigger price. The difference is Rs. 2.00.

🎯 Exam Tip: In word problems asking for "difference," always identify the two quantities and subtract the smaller from the larger to get a positive result.

Question 3. Mala went to textile shop and had bought chudithar for Rs. 58.70 and gave Rs. 100 to the shopkeeper. How much money did the shopkeeper return to Mala?
Answer:
Amount Mala gave \( = \) Rs. 100.00
Price of chudithar \( = \) Rs. 58.70
Money returned by shopkeeper \( = \) Amount given - Price of chudithar
\( = \) Rs. 100.00 - Rs. 58.70
\( = \) Rs. 41.30
When someone pays more than the item's cost, the shopkeeper gives back the extra money. This calculation shows the exact change Mala should receive.
In simple words: Mala gave Rs. 100 and the chudithar cost Rs. 58.70. To find the change, subtract the cost from the amount given. The shopkeeper returned Rs. 41.30.

🎯 Exam Tip: To calculate change, always subtract the item's cost from the total amount paid. Remember to align decimal points for accurate subtraction of money values.
