Question

Rakesh bought 50 articles for * 20,000. He sold 20 of them at a gain of 15%. At what rate must he sell the remaining articles so as to gain 30% on the whole ?
​

Answer 1

rate of article = rs560

cp of 50 articles =20000

overall profit%30%

profit=0.3x20000=6000

total sp = cp+profit=26000

cp of 1 article=20000/50=400

cp of 20 article =400x20=8000

%profit on 20 article =15%

profit on 20articles =0.15x8000=1200

sp of 20articles=cp of 20 article + profit on 20 article = 8000+1200 =9200

sp of 30 article = total sp-sp of 20 article =26000-9200=16800

sp of 1 article =16800/30=560

rakesh must sell the remaining 30 article at 560 each so as to get an overall profit of 30%
