Step-by-step explanation:
let no. of goods be x and price of goods be y
total price of goods=x × y=xy
marked price= xy + 24×xy/100
= xy+ 6xy/25=31xy/25
profit from 25% of goods=25×x/100 × 31xy/25
=x/4 ×31xy/25=31x²y/100
30% discount = 31xy/25×30/100=93xy/250
price after discount = 31xy/25 - 93xy/250=217xy/250
price of remaining 75% goods= 3x/4 × 217xy/250
=651x²y/1000
total earning= 31x²y/100 + 651x²y/1000
=961x²y/1000=0.961x²y
profit=0.961x²y-xy=xy(0.961x-1)
profit% = xy(0.961x-1)×100/xy
