Ratios: class has majors, non-majors in ratio 4 to 10

How do you solve this:


A physics class has majors and non-majors in a ratio of 4 to 10. If two more majors were to be added to the class, the ratio would then be 2 to 4. How many people are in the class?

the nonmajors doesnt change so make it equal
4:10 & 2:4 => 8:20 & 10:20
