From the last question number * questions corresponding to mantissa 9, it can be determined that questions =3.

The test range is 0.999999/0.3, 1.999999/ 1.3. . . 9.99999/9.3 Ten groups of data calculation, only

3.33333*0.3=0.999999 can satisfy the meaning of the question.

So I = love = number = learning = interest = problem = solution =3.
