Introduction

In this article, we will explore a simple math problem involving percentages and savings. Mrs. Muthu went shopping with a budget of $120 and spent a portion of it on meat and vegetables. We will calculate the amount of money she spent on these items and determine how much she saved.

Understanding the Problem

Mrs. Muthu had $120 to spend on shopping. She spent 12% of the money on meat and 25% on vegetables. To find out how much she spent on these items, we need to calculate 12% and 25% of $120.

Calculating the Amount Spent on Meat

To calculate 12% of $120, we can use the following formula:

Amount spent on meat = (12/100) x $120

Using a calculator or performing the calculation manually, we get:

Amount spent on meat = (12/100) x $120 = $14.40

Calculating the Amount Spent on Vegetables

To calculate 25% of $120, we can use the following formula:

Amount spent on vegetables = (25/100) x $120

Using a calculator or performing the calculation manually, we get:

Amount spent on vegetables = (25/100) x $120 = $30

Calculating the Total Amount Spent

To find out the total amount spent on meat and vegetables, we need to add the amounts spent on each item:

Total amount spent = Amount spent on meat + Amount spent on vegetables Total amount spent = $14.40 + $30 Total amount spent = $44.40

Calculating the Amount Saved

To find out how much Mrs. Muthu saved, we need to subtract the total amount spent from the initial budget:

Amount saved = Initial budget - Total amount spent Amount saved = $120 - $44.40 Amount saved = $75.60

Conclusion

In this article, we calculated the amount of money Mrs. Muthu spent on meat and vegetables and determined how much she saved. We used percentages to find out the amounts spent on each item and then subtracted the total amount spent from the initial budget to find the amount saved.

Real-World Applications

This problem can be applied to real-life situations where we need to calculate percentages and savings. For example, if you are planning a trip and have a budget of $1000, you may need to calculate the amount spent on transportation, accommodation, and food. By using percentages and savings, you can determine how much you have left for other expenses.

Practice Problems

Try solving the following problems:

If you have a budget of $500 and spend 15% on clothes, how much do you have left?
If you have a budget of $200 and spend 20% on entertainment, how much do you have left?
If you have a budget of $300 and spend 10% on groceries, how much do you have left?

Answer Key

Amount left = $500 - (15/100) x $500 = $425
Amount left = $200 - (20/100) x $200 = $160
Amount left = $300 - (10/100) x $300 = $270
