Answer»

Answer:

Step-by-step explanation:

Reduction of 20% = 1/5

This means that,

Orginal price is 5 and new price is 4

And we KNOW that quantity is inversely proportional to price,

i.e. quantity purchased by person is 4 at 5 rs and after reduction quantity purchase by person is 5 at 4 rs

Increment in quantity is 1 which us equal to 3.5 kg

Initially person was PURCHASING 3.5×4=14kg rice

Original price is 77/14= 5.5rs
