It's easy. It is a only simple high school algebra.
First let the original price be x. Then add 3 to x.
Second let the amount of potatoes that can be bought with price x be y
and do the maths: 60 cents can buy how many kilos for the price of x?
60/x = y
60 cents can buy how many kilos for the price of x+3?
60/(x+3) = y - 1
from now on it's very easy, you should be able to do it on your own.
