Video narration
Canteen mein aapka pasandida snack achanak mehnga ho jaye ya milna hi band ho jaye - kya dukandaar keemat manmaane dhang se tay kar raha hai? Bahut se vidyarthi wahi snack khareedna chahein aur khareedne ki kshamata bhi rakhein, to yah demand, yani maang, hai. Maang keval ichchha nahin, khareedne ki ichchha aur kshamata dono hai. Supply, yani aapoorti, ka matlab hai, dukandaar ke paas bikri ke liye kitne snack uplabdh hain. Snack kam hon aur kharidaar zyada, to keemat badhne ka dabaav banta hai. Yahi asli mod hai: keemat manmaani nahin hoti. Ulta, snack zyada hon aur kharidaar kam, to keemat ghatne ka dabaav rahta hai. Jis keemat par vidyarthi jitna khareedna chahte hain, dukandaar utna hi bechne ko taiyaar hota hai, vah equilibrium, yani santulan, hai. To shuruaat ka jawaab saaf hai: kharidaar bahut, snack kam - demand supply se adhik; isliye dukandaar adhik keemat le sakta hai.
