Need help on 3rd grade word problem

Question

There are 376 first, second and third graders going to see a play.

The number of 3rd graders is 28 less than 200.

The number of 2nd graders is twice the number of 1st graders.

How many students from each grade are going?

Answer 1

172 3rd

153 2nd

51 1st

Answer 2

200-28=172            172  students for 3rd graders

376-172=204          68 students for 1st graders

204/3=68

68x2=136               136 students for 2nd graders
