        //looping till investment is atleast 1
        while(inv<5000){
            //finding investment
            inv=2500*Math.pow((1+7.5/100),year);
            //incrementing year
            year++;
        }
        //printing the number of years required
        System.out.println("Number of years required is "+(year-1));
