Step-by-step explanation:

mana ki chini ka bhav x rupee per kg tha

to 140 rupee me 140/x kg chini aata tha

ab chini ka bhaav 10% kam ho gaya

naya bhaav = x - x/10 = 9x/10

ab 140 rupee me 140/(9x/10) kg chini ayega

= 1400/9x kg

prashn ke anusar

1400/9x - 140/x = 1/2 (500 gram = 1/2 kg)

(1400 - 1260)/9x = 1/2

140/9x = 1/2

9x = 140*2

x= 280/9 per kg
