At a bus stop 20 students were standing in four groups. The first group contained

four students more than the second. The second group contained one student less
than the third. The fourth group contained twice as many students as the second
group. How many students were in each group?

3 answers

If the 4 groups have w,x,y,z respectively, then

w = x+4
x = y-1
z = 2x
w+x+y+z = 20

Now just crank it out.
