مسالة حيرتني لضعفي في الرياضيات icon36icon36
فاردتكم ان تشاركوني في الحل

شخص جائته فاتورة التيلفون بـ 450 دينار
أستلف من أبوه 250 دينار ومن امه 250 دينار

... ... ... ... بقى معاه 500 دينار.. سدد الفاتورة ,بقى معة 50دينار
... ...
رجّع لأبوه 10 دنانير ,ورجّع لأمّه 10 دنانير,اتبقى معة 30 دينار

و هكذ نقول استلف من ابوة 240 دينار ومن أمّه 240 دينار ,وهو معة 30 دينار

,,,,,,,,,, 240+240+30=510 دينار

من اين جاءت 10 دنانير المتبقية؟

[لغريب]

السلام عليكم
بعد تفكير طويييييييييييييل عرفت الحل هههههههه

[masrour farah]

رياصيا واقتصاديا لا يمكن أن يكون للدين والمتيسر من المال
نفس الإشارة .
الدين المتبقي هو 240 + 240 = 480 دج وله إشارة سالبة .
أما المتبقي هو 30 دج بإشارة موجبة .
إذا المعادلة لا يمكن أن تكون بهذا الشكل .
اما اللعز بالضبط فالله أعلم ....

[نوركيم]

غير منطقية ..
لانك ادخلت الدين و هو عندك سالب .. مع الباقي من الدين وهو في جانب أخر موجب لديك
نفرض ان ابوك اعطاك 240 و امك 240 المجموع = 480
و دفعت اجر الفاتورة ب 480 اذن الباقي عندك = 0
يوجد في جيبك 50 دينار ملكك ...
و اعطيت لابوك 10 ولامك 10 الباقي
لايمكن لك ان تجمع الباقي الذي عندك 30 مع 480

و لكن

كان من المفروض انك تقول 240 + 240 + 10 + 10 = 500


شكرا على الموضوع الجميل جدا ..

****
اتذكر ان هذا اللغز طرح علي مرة من زمن وكسرت راسي فيه .. لكنه في الاصل غير منطقي ...

[zineb o]

30 حسبت مرتين ، من مفروض لما تحسب الباقي تنقصه من الدين
(240+10)+(240+10)=500

[لغريب]

السلام عليكم
بطريقة أخرى 30 جزء من 240+240
وعندما نريد ذكرها نقول:
450 (دين سونلغاز)+10+10+30=500 مجوع الدين الكلي..
وللتوضيح أكثر سؤال:
عند قولنا 240+240+30=510
ماهو المبلغ المتحصل عليه .هل مجموع الدين أو مجموع المال الباقي؟؟
