Let the initial price of sugar be Rs 100p.
Therefore, 20% reduction= 20% of Rs 100p=(20/100)x(100p)=20p
Reduced Price = Original Price - Reduction in Price=100p-20p=80p
Price of 3kg= Rs 360
Price of 1kg= 360/3= Rs 120
Reduced price=80p
or, p= 120/80= 1.5
Therefore, Initial price = 100p= 100x1.5= 150
Reduced Price= 80p= 80x1.5= 120
Therefore, 20% reduction= 20% of Rs 100p=(20/100)x(100p)=20p
Reduced Price = Original Price - Reduction in Price=100p-20p=80p
Price of 3kg= Rs 360
Price of 1kg= 360/3= Rs 120
Reduced price=80p
or, p= 120/80= 1.5
Therefore, Initial price = 100p= 100x1.5= 150
Reduced Price= 80p= 80x1.5= 120
