ঘড়িটির ক্রয় মূল্য নির্ণয় 📉
একটি ঘড়ি ১৫০ টাকায় বিক্রয় করায় ২৫% ক্ষতি হয়েছে। এর ক্রয় মূল্য বের করতে হবে। 🤔
সমস্যাটির বিশ্লেষণ 🔎
- বিক্রয় মূল্য: ১৫০ টাকা
- ক্ষতির শতকরা হার: ২৫%
সমাধানের ধাপ 🪜
- ধরি, ক্রয় মূল্য = x টাকা
- ক্ষতির পরিমাণ = x এর ২৫% = (২৫/১০০) * x = x/৪ টাকা
- বিক্রয় মূল্য = ক্রয় মূল্য - ক্ষতির পরিমাণ
- সুতরাং, ১৫০ = x - x/৪
- => ১৫০ = (৪x - x)/৪
- => ১৫০ = ৩x/৪
- => ৩x = ৬০০
- => x = ৬০০/৩
- => x = ২০০ টাকা
ফলাফল 🎁
অতএব, ঘড়িটির ক্রয় মূল্য ২০০ টাকা। 🎉
