Solution
Case I : Milkman sells 120 litres of milk for Rs. 3,360/-
=> S.P. per litre = Rs. $\frac{3360}{120}$
= Rs. 28
Case II : Milkman sells 240 litres of milk for Rs. 6,120/-
=> S.P. per litre = Rs. $\frac{6120}{240}$
= Rs. 25.5
$\therefore$ Required discount = Rs. (28 - 25.5) = Rs. 2.5
Case I : Milkman sells 120 litres of milk for Rs. 3,360/-
