Question

A trader mixes the flour 15 kg of Rs.15 per kg with 20 kg of Rs.18 per kg. If she has to gain Rs.80, at what price per kg must she sell the mixture?

Answer 1

Answer:

cost of 15/kg flour is 15X15= 225/-

cost of 18/kg flour is 18X20=360/-

total cost of mixture = 225+360=585

if profit is 80/-, then S.P. will be 585+80=665/-
