Mehangai: daam kyun badhte hain aur kise zyada chubhte hain?
Mummy ne kaha: 'Pyaaz ke daam doguna ho gaye!' Ek sabzi ka daam itna kaise badh jaata hai, aur kya iska asar sab par ek jaisa hota hai?
Socho pehle… phir dekho jawab
Daam do kaaran se badhte hain: cheez kam ho jaaye (supply), ya lene wale badh jaayein (demand). Aur mehangai un parivaron ko zyada chubhti hai jinki kamai ka bada hissa khaane par jaata hai.
Supply: kam baarish ho ya purana stock khatam ho jaaye aur nayi fasal abhi na aayi ho, toh mandi mein pyaaz kam pahunchte hain. Kam maal, wahi grahak — daam upar.
Demand: tyohaar par sab mithai aur kapde ek saath khareedte hain, toh in cheezon ke daam badh sakte hain.
Pratishat se samjho (numbers sirf udaharan): pichhle saal ₹40 kilo, ab ₹48 kilo. Badhat ₹8. (8 ÷ 40) × 100 = 20%. Yahi us ek cheez ki '20% mehangai' hai.
Kise zyada chubhti hai: jis ghar ki kamai ka bada hissa khaane par jaata hai, wahan sabzi mehngi hone ka asar sabse bada hota hai. Isliye mehangai sirf number nahi, har ghar ki thaali ka sawaal hai.
Ghar pe try karo
Bade ke saath ek 'daam diary' banao: doodh, aata aur ek sabzi ka aaj ka daam likho. Ek mahine baad wahi daam dobara likho aur farak nikalo.
Wow!
Kabhi-kabhi kisi sabzi ka daam ek saal mein doguna se bhi zyada ho jaata hai — aur uska sabse bada asar rasoi ke budget par padta hai!
Mummy-Papa ke liye
Aaj bachche ke saath doodh, aata aur ek sabzi ka daam ek kaagaz par likhiye; agle mahine wahi daam saath milkar milaiye.
