সমস্যার বিবরণ
জুয়েলের বয়স তার পুত্র সুমনের ??য়সের দ্বিগুণ। ১০ বছর পূর্বে তাদের বয়সের অনুপাত ছিল ৮:৩। জুয়েল এর বর্তমান বয়স কত?
সমাধানের ধাপ 🪜
- ধাপ ১: চলক ধরা
- ধরি, সুমনের বর্তমান বয়স = x বছর
- সুতরাং, জুয়েলের বর্তমান বয়স = 2x বছর
- ধাপ ২: ১০ বছর পূর্বে বয়স
- ১০ বছর পূর্বে সুমনের বয়স ছিল = (x - 10) বছর
- ১০ বছর পূর্বে জুয়েলের বয়স ছিল = (2x - 10) বছর
- ধাপ ৩: অনুপাত তৈরি
প্রশ্নমতে, (2x - 10) / (x - 10) = 8 / 3
- ধাপ ৪: সমীকরণ সমাধান
আর গুণন করে পাই,
3(2x - 10) = 8(x - 10)
6x - 30 = 8x - 80
2x = 50
x = 25
- ধাপ ৫: জুয়েলের বর্তমান বয়স নির্ণয়
জুয়েলের বর্তমান বয়স = 2x = 2 * 25 = 50 বছর
ফলাফল 🎉
সুতরাং, জুয়েলের বর্তমান বয়স ৫০ বছর।
