Ravish bought 100 articles 4000. He sold 20 of them at a gain of 5%. at what gain percent must he sell the remaining articles so as to gain 20% on the whole

Answers (1)

Cost price of  100 articles = 4000.=> 40 per article 

He sold 20 of them at a gain of 5%. So the selling price  =  40x105/100 = $ 42 per article 

Selling price of 20 article = 42x20= 840

For 20 % gain on whole the total selling price = 4000x120/100= 4800

Total Selling price of remianing 80 articles = 4800− 840 = $ 3960

  Selling price of ramaining articles =  3960/80= 49.5 per article

Gain % = (49.5-40)x100/40 = 23.75 %
