agar aap shop keeper ho .. aap ke paas ek customer aata hai aur 70 Rs ka ek gift leta hai aur aap ko 100 Rs ka note deta hai .. aap ne abhi abhi hi shop open ki hai is lie change nahi hota ... aap jaldi se sath wali shop per jate ho .. aur 100 ka change le ker aate ho aur aa ker customer ko change dete ho wo chala jata hai .. kuch dair baad sath wali shop wala ghusse se aa jata hai ke mujhe naqli note de gye ho .. yeh lo apna note aur mere paise wapis karo .. ab aap ko us ke paise wapis karne parte hain ..
ab aap ne 100 Rs sath wali shop wale ko de diya .. 30 Rs us customer ko change bhi diya tha .. aur gift bhi 70 Rs ka tha .. aur 100 Rs wala note bhi naqli tha ..
ab yeh batayein ke aap ka total nuqsan kitne ka hua ?
