According to the data in the figure, the frequency of score greater than or equal to 80 points =(0.04+0.03)× 10=0.7.

The number of students with a score of 80 or more is 0.7×500=350.

The frequency of grades in [90, 100] is 0.03× 10=0.3.

When the sample size is 60, the number of students whose grades are within [90, 100] should be 60×0.3= 18.

So the answer is: 350, 18.
