Questions and Solutions

Question 1

What about you? Do you also find Maths difficult? What is the most difficult thing in your Maths books? What do you think is the easiest lesson?

Solution: This question asks for your personal opinion about mathematics. Your answers may differ from others. It's a good idea to think about what you find challenging and what you find easy in your Maths book. For example, some students might find multiplication tables difficult, while others might find addition the easiest. Discussing with your classmates can help you see different perspectives. Remember, the goal is to understand and practice, and it's okay to find some topics harder than others.

Question 2

Find out: how much for a cup of tea? Ask people and find out the cost of a cup of tea at a tea stall and at a hotel.

Solution: This is an observational activity. You need to ask different people or visit different places to find out the prices. For example:

At a local tea stall, a cup of tea might cost around Rs 10.
At a hotel or a restaurant, a cup of tea might cost Rs 20 or more.

Discuss these prices with your friends and note down the differences. This helps you understand how prices can vary based on the location and type of establishment.

Question 3

If a person who runs a tea stall earns Rs 30 in a day, how much will he earn in 10 days? And in a month? How did you get the answer? Discuss.

Solution:

To find the earnings in 10 days, we multiply the daily earning by 10.

Earning in 1 day = Rs 30

Earning in 10 days = Rs 30 \times 10

Calculation: $30 \times 10 = 300$

So, the person will earn Rs 300 in 10 days.

To find the earnings in a month, we need to know the number of days in the month. Let's assume a month has 30 days.

Earning in 30 days = Rs 30 \times 30

Calculation: $30 \times 30 = 900$

So, the person will earn Rs 900 in a month (assuming 30 days).

How we got the answer: We used multiplication. To find the total earnings for multiple days, we multiply the earning per day by the number of days.

Question 4

Hariya and Babu want to buy a handcart for Rs 300. Hariya has taken a loan of Rs 300 from a bank for six months. He will pay Rs 51 every month to the bank. Babu has taken a loan of Rs 300 from Chunnilal. After six months, he will pay Rs 360. Who paid more? How much more?

Solution:

First, let's calculate how much Hariya paid in total.

Hariya's monthly payment = Rs 51

Loan period = 6 months

Total amount paid by Hariya = Monthly payment \times Number of months

Total paid by Hariya = Rs 51 \times 6

Calculation: $51 \times 6 = 306$

So, Hariya paid a total of Rs 306.

Now, let's look at Babu's payment.

Babu took a loan of Rs 300 and paid Rs 360 after six months.

Total amount paid by Babu = Rs 360

To find out who paid more, we compare the total amounts paid:

Hariya paid = Rs 306

Babu paid = Rs 360

Since 360 is greater than 306, Babu paid more.

To find out how much more Babu paid, we subtract Hariya's total payment from Babu's total payment:

Difference = Babu's total payment - Hariya's total payment

Difference = Rs 360 - Rs 306

Calculation: $360 - 306 = 54$

So, Babu paid Rs 54 more than Hariya.

Common mistakes

Errors in multiplication, especially with larger numbers or zeros.
Miscalculating the number of days in a month for earnings.
Confusing the principal loan amount with the total amount to be repaid.
Incorrectly adding monthly payments to find the total repayment.

Revision tips

Practice the multiplication problems in the solutions carefully.
Create your own scenarios for calculating earnings and loan payments.
Pay close attention to the difference between the initial loan amount and the total repayment.
Review the steps for calculating earnings over 10 days and a month.
