Answer 2

Given : SP of 4 kg is equal to CP of 5 kg

Let the cost price be Rs x.

$SP of 4 kg = CP of 5 kg$

               $= 5x$

Hence,

SP of 1 kg $=\frac{5x}{4}$

                  $=1.25x$

The selling price is greater than the cost price,

$Profit\% =\frac{SP-CP}{CP}\times 100$

$Profit\% =\frac{1.25x-x}{x}\times 100$

$Profit\% =\frac{0.25x}{x}\times 100$

$Profit\% =0.25\times 100$

$Profit\% =25\%$

The discount percentage is,

$(100+25)x=25\times 100$

               $x=\frac{25\times 100}{100+25}$

               $x=\frac{100}{5}$

                $x=20\%$
