Only 2/5 of the students doubted. if 600 students were no doubters, how many students were there in all?

1000 students

Step-by-step explanation:

First, what fraction is left of 2/5? 3/5!! Now you can set up a proportion. 3/5 is equal to 600/??? Simple. 5 * 600 = 3000. 3000 / 3 = 1000. That's the total number of students, your answer!

For further understanding:

This means that 400 students doubt. 400/1000 and 2/5 both equal 0.4, so that is a clue to know you are right.

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
