Question

You want to prepare a test that contains 20 questions worth 50 points overall. How many 2-point and 4-point questions can you include in the test?

Answer 1

5, 10
10, 10
12, 8
15, 5

Answer 2

let 'x' be the number of 2-point questions
'y' be the number of 4-point questions
since there are 20 questions all then,
x + y = 20 -----equation 1
since it's worth 50 points then,
2x + 4y = 50 -----equation 2
using the two equations, find x and y
