jst think 100Rs for 1 kg is the CP(100/kg) now you want 125 Rs => 1.25 kg (100/kg) => 1kg already for pure butter => .25 kg for adulterated fat => .25/1.25 => 20%
Hi Puys, I need help with this particular ArunSharma problem.
A dishonest grocer professes to sell pure butter at cost price, but he mixes it with adulterated fat and thereby gains 25%.Find the percentage of adulterated fat in the mixture assuming that adulterated fat is freely available. Ans:20%
