Answer 2

Original price and consumption is Rs. 4.16 and 71.96 kg resp. and current price and consumption are Rs. 5 and 60 kg resp.

Step-by-step explanation:

Since we have given that

Quantity less to be purchased = 12 kg

Amount = Rs. 300

Rate of growth = 20%

So,Original price becomes,

$\dfrac{Amount}{Quantity}\times \dfrac{Growth\%}{100+Growth\%}\\\\=\dfrac{300}{12}\times \dfrac{20}{120}\\\\=Rs.\ 4.16$

Current price would become

$\dfrac{Amount}{Quantity}\times \dfrac{Growth\%}{100}\\\\=\dfrac{300}{12}\times \dfrac{20}{100}\\\\=Rs.\ 5$

Original consumption is given by

$\dfrac{300}{4.16}=71.96\ kg$

Current consumption is given by

$\dfrac{300}{5}=60\ kg$

Hence, Original price and consumption is Rs. 4.16 and 71.96 kg resp. and current price and consumption are Rs. 5 and 60 kg resp.
