Question

A shopkeeper purchases 60 kg of tea at rs 120 per kg amd mixed it with 40kg of tea costing rs 200 per kg.At what rate per kg must he sell this mixture to make a profot of rs 20%

Answer 1

Answer:

total cost price of shopkeeper= (60*120) +(40*200) =15200

let he sell at xrs/kg

(x*100-15200/15200) *100=20/100

(x*100-15200/15200) *100=1/5

(x*100-15200/15200) =1/500

100x-15200=15200/500

100x=15200+152/5

x=(15200+30.4) /100

x=152.304
