Let the cost price of rice be X and the profit made on this will be X x 20/100. Selling price would be X + X x 20/100 = 160.
X = 800/5 = Rs.133.33

Where doesthis 800 nd 5 come frm???
X + X x 20/100 = 160
X + X x 1/5 = 160
X + X/5 = 160
(5X + X)/5 = 160
6X/5 = 160
6X = 160 x 5
6X = 800
X = 800/6
X = 133.33
I hope now it is clear where from 800 and 6 came. By mistake 5 was typed.
thta wat i am talkin about
ok sir u hav solved it by the symbol usin x bt in my book they had use the fomula of rate%=percentage\ base ...so can i solve it by ur method because ur method is vry ezy in my book so freaking complicated plzz tell me ?
Dear Aslam, this is the proper method. No problems, you can solve this question in exams by this method.
sir i had not understnad the 4th portion how does this come ? (5x+x)\5
It has come because of addition of fractions by taking LCM.
160*120/100 i think this method is enough
Dear Cheetah, it should be (160/120)X100 = 133.33
