Question

Hari bought 20 kg of rice at R 36 per kg and 25 kg of rice at 32 per kg. He mixed the two varieties and sold the mixture at 38 per kg. Find his gain per cent in the whole transaction

Answer 1

hey mate
the cost price of total mixture=(20×36)+(25×32)=Rs1520
and the selling price of total mixture=45×38=Rs1710
hence the profit=SP-CP=1710-1520=Rs190
so, the gain percent=(gain/CP)×100
gain percent=(190/1520)×100=12.5%

hope it helps u
