A person sold an article at a profit of 15% if he sold it for Rs 81 less , his loss would have been 12% find the cost price of the article. ​

let cp be x

sp= 115x/100 ---(when 15%gain)

sp = 88x/100(when 12% loss

according to question

115x/100 - 88x/100 = 81

or, (115x-88x)= 8100

or, 27x = 8100

or, x= 8100/27

x = 300

hence cp is RS 300

answer:

24pi or letter c

114 plus 113 times 2 and 114 times 3
