The house was decorated with colorful rangoli, and the sweet shop nearby was filled with the aroma of freshly made laddoos and barfis. \n\n**The Problem:**\nRiya\u2019s mother had given her the task of buying sweets for their family gathering. \u201cMake sure to get 3 boxes of laddoos and 2 boxes of barfis,\u201d she instructed, \u201cand don\u2019t forget to ask for the price!\u201d \n\nWhen Riya reached the shop, she saw that the shopkeeper, Mr. Sharma, was busy with other customers. Riya waited patiently and then approached him with her order. \n\n\u201cUncle, how much for the sweets?\u201d she asked. Mr. Sharma smiled and replied, \u201cRiya, laddoos are \u20b950 per box, and barfis are \u20b970 per box. But I also have a special deal: if you buy more than 4 boxes in total, I can give you a discount of \u20b920!\u201d\n\nRiya thought for a moment. She needed to calculate how much money to bring. She had \u20b9300 saved up from her birthday and wanted to make sure she had enough to buy the sweets for the whole family.\n\n**Let\u0027s Solve the Mystery:**\nRiya knew that she wanted to buy 3 boxes of laddoos and 2 boxes of barfis. She quickly set up her equation:\n\nLet the number of boxes of laddoos be \\( x \\) and the number of boxes of barfis be \\( y \\). \n\n1. **Finding the Total Cost:**\n   - Cost of laddoos: \\( 3 \\times 50 = \u20b9150 \\)\n   - Cost of barfis: \\( 2 \\times 70 = \u20b9140 \\)\n   - Total cost without discount: \\( 150 + 140 = \u20b9290 \\)\n\n2. **Applying the Discount:**\n   - Since Riya is buying 5 boxes (more than 4), she can use the discount:\n   - Total cost after discount: \\( 290 - 20 = \u20b9270 \\)\n\n3. **Checking the Budget:**\n   - Riya had \u20b9300. She quickly calculated:\n   - Remaining money after buying sweets: \\( 300 - 270 = \u20b930 \\)\n\n**The Solution:**\nWith her calculation complete, Riya confidently told Mr. Sharma, \u201cI\u2019d like to buy 3 boxes of laddoos and 2 boxes of barfis. That comes to \u20b9290, and I can get a \u20b920 discount, right?\u201d\n\nMr. Sharma nodded, impressed. \u201cThat\u2019s correct, Riya! You\u2019ve done your math well. Here are your sweets!\u201d\n\nRiya beamed as she took the boxes of sweets, knowing she had made her mother proud and saved a little money too. She raced home, ready to surprise her family with the delicious treats.\n\n**Conclusion:**\nRiya learned that math is not just about numbers in a book; it\u2019s about solving real-life problems that make her adventures in everyday life exciting. She felt like a hero, having used her math skills to bring joy to her family during the festival of Diwali!\n\n---\n\n**Lesson Takeaway:**\nMath can help us in our daily lives, especially when it comes to budgeting and making purchases. Understanding simple equations and calculations can make tasks easier and more enjoyable!",
