If digit h is the hundrendths' digit in the decimal d = 0.2h6, what is the value of d, rouded to the nearest tenth ?
(1) d <1/4
(2) h < 5
Taking (1)... if d < 1/4, then h can take any of the values from 0 to 4.
hence value of "rounded" d can not be found. So no uniqe answer
Taking (2).. if h < 5, Again the value of "rounded" d can not be found.
Even taking (1) and (2) together, you get nothing...
So the answer can not be found.
