    What is the formula that I will use in calculation ??

    It has been found that in a small town number of uneducated people decrease each 5 year by 40% of the previous year ..

    The number of uneducated people in 2005=70

    Calculate number of uneducated people in 2010??


    what is the formula that I will use?

    Is it true that:

    number of uneducated people in 2010=70*(40/100)=28

    EDIT: Mistake is that you have calculated the decrease rather than the exact number ..
