    You have to calculate the time in days.

    Given --

    8 cows can eat 7 bags of feed in 9 days .

    Now think if only one cow eats the entire stuff that was to be fed to 8 cows, it will take more days to finish 7 bags.

    that is - One cow will finish 7 bags in 9 x 8 = 72 days.

    Hence we have --

    1 cow can eat 7 bags of feed in 72 days.

    Hence 12 cows will eat the entire feed (7 bags) in = 72/12 = 6 days...... ANSWER

    9 x 2/3 = 18/3 = 6 days

    8 * 7 * 9 = 12 * 7 * x

    504 = 84x

    x = 504/84

    x = 6 days <–––––––
