2. when we calculate loss of shopkeeper , we will only count form his side , not from other sides. we will just calculate his transaction and his products.

first we will see case 3

in case 3 fake note of 1000 was given to the shopkeeper , and products of 1000 were taken away.
the fake note has no value , so consider it zero transaction or No transaction.
and products of 1000 were given to the lady , the products are owned by shopkeeper
so the loss of shopkeeper is 1000 rupees only.

in 2nd case , the shopkeeper took the fake note , paid 800 from cashbox , and product of 800 rupees gone.
fake note has no value , so this is not a transaction.
product and cash back 200+ 800 = 1000 , so total loss is 1000 rupees only.

in 1st case , just rename the "other shopkeeper" as CASH BOX
thats all. the total loss is still 1000 rupees

اس مسلہ کو پریکٹیکل سے سمجھنے کی کوشش کرتے ہیں

تھوڑی دیر کیلئے اپنے آپ کو دوکاندار سمجھ لیجئے

ایک لڑکی آتی ہے آپکو 1000 کا جعلی نوٹ دے جاتی ہے

آپ اسے 200 کا سامان دیتے ہیں یہ آپکا نقصان ہوا اور 800 کا بقایا دینا ہے
اب آپکے پاس چینج نہیں ، آپ نے دوسرے دوکاندار سے جعلی نوٹ کے بدلے 800+ 200=1000 کا چینج لیا جو آپکا نہیں اور اسمیں سے 800 لڑکی کو بقایا واپس کیا اور 200 دوسرے دوکاندار کا خود رکھ لیا ۔۔

لڑکی آپکا 200 مالیت کا سامان+800 دوسرے دکاندار کا بقایا= 1000 لے گئی

اب آپنے 200 کا سامان دیا اور 200 دوسرے دکاندار کا واپس آگیا ۔۔آپکا نقصان برابر یعنی 0

اب دوسرا دوکاندار 1000 کا جعلی نوٹ واپس لایا آپ اسکو جعلی نوٹ کے بدلے کہیں سے 1000 ارینج کردیں یہی آپکا نقصان

یا پھر جنکو اسطرح سمجھ نہیں آئی وہ دوسری طرح سمجھ لیں

جب دوسرا دکاندار 1000 کا جعلی نوٹ واپس لایا تو اسے اسی کا
200 چینج + 800 اپنی طرف سے =1000 واپس دیں، یہ 800 آپکا دوسرا نقصان ہوا۔۔۔ اب آپکا پہلا نقصان 200 کا سامان اور دوسرا نقصان 800= 1000 ٹوٹل

اب یوں سمجھ لیں جو 1000 آپنے دوسرے دوکاندار سے جعلی نوٹ کے بدلے لیا وہ جعلی نوٹ کی واپسی پر آپنے واپس کردیا۔۔

لڑکی آپکے پاس 1000 کا جعلی نوٹ چھوڑ گئی اور آپکا 200 کا سامان +800 بقایا= 1000 لے گئی

4. bilkul aasan hae 1200 Rs ka nuqsan ho gaya

1000 Rs ke jaali note+200 Rs

post purani hae mager main ne aaj he dekhi

5. ji nhe , nuqsaan ki calculation theek nhe ki aap nay.

jaali note ki koi value nhe , uss ko consider nhe karein

jo value waali cheezein wo lay ker gai wo hein 800 ka cash aur 200 ki product

800+ 200 = 1000
aur yehi nuqsaan hai

6. ok----mager jaali note bhi tu hae na ?

7. agar mein aap ko 10,000 k jaali notes day don , to aap ko kia nuqsaan hoga ? kuch bhi nhe. lekin nuqsaan wohi hoga , agar mein fake money k badlay mein koi cheez lon ga. iss liaay fake note apni zaat mein koi nuqsaan ya faida nhe hai ,
