Question

A super bazar prices an item in rupees and Paise so that when 4% sales tax is added , no rounding is exactly in n rupees, where n is a possitive integer. Find the smallest value of n .

Answer 1

let the price be x rupees y paise =100x+y paise

so (100x+y)x104/100=n(rupees)x100

or 100x+y=nx100x100/104=nx1250/13

so n should be a multiple of 13

taking n=13

we get 100x+y=1250 or 12.50 rupees answer

Answer 2

Let price be n rupee y paise

(100x+y)*104/100=n(rupees)*100
