    Thumbs up Re: a a tricky one

    If for every 3 wrappers I get 1 soap free ( with wrapper of course )
    How many soaps do I need to buy to get 20 soaps

    Easy one.....
    for every 3 soaps we get 1 more soap

    3=4(3+1)
    6=8(6+2)
    9=12(9+3)
    12=16(12=4)
    15=20(15+5)

    so to get 20 soaps we have to buy 15 soaps......


    I think I am correct.....
    correct me if i am wrong!!!!!!!!!!!

    Re: a a tricky one

    251/11 = 22 soaps(22 scraps) and 9 scraps
    22 scraps leaves 2 more soaps(22+2(2 scraps))
    that 2 scraps will be added with 9 scraps to get 1 more soap(22+2+1(1scrap))

    So final answer is 25 soaps and 1 scrap remaining......
