A bookseller sells a book at a profit of 10%. If he had bought it at 4% less and sold it for 60 paisa more, he would have gained 18 ¾ %. What does it cost to the bookseller? (a) Rs.11 (b) Rs. 4 (c) Rs. 10 (d) Rs. 15

• let cp=100% sp=110%(profit is 10%)
  new cp=96%(4% less) new sp=110%+60/100(convertin in rs)
  gain=18 3/4% therefore sp=(96+ 96of 18 3/4%)=114%
  now equating the sp,
  110%+6/10=114%
  4%=6/10(rs)
  100%=rs15

• Well,lets c.p=x,so as per my given data
  s.p=110/100*x........(1)
  now,when it sold .6rs more then s.p=96/100*(x+.6)....(2)
  from (1) and (20,we have
  110/100*x=96/100*(x+.6)
  after calculating we will get x=r.s 4.
  so answer will be(b).
