Answer:

To find this out, turn 3/8 into decimal form, (0.375).

Now, turn each percent into standard form. (Also decimal form)

26% = 0.26, 27% = 0.27, 37% = 0.37, and 38% = 0.38.

The decimal closest to 0.375 is 37%.

X - the number of the questions worth 2 points
y - the number of the questions worth 4 points

$x+y=50 \\
2x+4y=110 \\ \\ 
\hbox{from the 1st equation:} \\
y=50-x \\ \\
\hbox{substitute 50-x for y in the 2nd equation:} \\
2x+4(50-x)=110 \\
2x+200-4x=110 \\
-2x=-90 \\
x=45 \\ \\
y=50-45=5$

The answer:
There are 45 questions worth 2 points and 5 questions worth 4 points.
