The sum of three consecutive multiples of 8 is 888. Find the multiples.
Let the three multiples of 8 are: x, x + 8 and x + 8 + 8 = x + 16.
According to the condition, we have
        [x] + [x + 8] + [x + 16] = 888
or           x + x + 8 + x + 16 =  888
or                          3x + 24 =  888
 Â
  Transposing 24 to RHS, we have
                              3x = 888 - 24 = 864
 Â
  Dividing both sides by 3, we have
                                  Â
                                         x = 864 3 = 288
∴                                   x + 8 = 288 + 8 =296
and                                x + 16 = 288 + 16 = 304
    Thus, the required multiples of 8 are: 288, 296 and 304.
