Question

A shopkeeper mixes 26 kg of wheat which cost rs. 20 a kg with 30 kg of wheat which cost rs. 36 3 kg and sells the mixture at rs. 30 3 kg. Find the profit percent.

Answer 1

pls mark it as brainliest
now the sp=30.3/kg

number of kgs= 56kg

so selling price of whole mixture is 30.3*56= 1696.8

cost price= 26*20+30*36.3=520+1089=1609
now profit= sp-cp=1696.8-1609=87.8
profit%= 87.8*100/1609=5.45
