Answer 1

Answer:

let the actual cost of sugar=x

therefore, the sugar cost decrease=20%

x=240

$240 + 20\% \\ 288 \div 12 \\ 24$

the cost of actuall each kg sugar is=24

the cost of decreased each kg sugar =28.8

Answer 2

Given :

Paying capacity = Rs. 240

Lost in quantity = 20%

Extra quantity = 12 kg

To find : the value of original price in kg.

Solution:

Value of original price is derived from :

$\dfrac{Paying\ capacity}{Quantity}\times \dfrac{r\%}{100-r}\\\\=\dfrac{240}{12}\times \dfrac{20}{80}\\\\=\dfrac{20}{4}\\\\=Rs.\ 5$

Hence, the original price of sugar is Rs. 5 per kg.
