Question

A super bazar prices an item in rupees and paise so that when 4% sales tax is added, no rounding is neccessary because the result is exactly in 'n' rupees,where 'n' is a positive integer.Find the smallest value of 'n'?

Answer 1

Solution:-
Let the final rupees is 'n' and initial before tax is 'x' Rs.
So according to the question
x + (4/100)x = n
x + (1/25)x = n
(25x + x)25 = n
26x/25 = n
x = 25n/26
Now, n must be a factor of 26 which are 1, 2, 13 and 26. For x to be terminating decimal n can be 13 or 26. 13 is smaller.
n = 13  Answer

Answer 2

answer is 13 because 26,13 13 is small number
