short-answer questions are worth 3 points. If the test has 30 questions, how
many multiple-choice questions are there?
O
A. m + s = 5
2m + 3s = 105
O
B. m + s = 75
2m + 3 = 30
O
c. m. s= 30
2m. 3s = 75
O
D. m + s = 30
2m + 3s = 75

Answer 1

D. m+s=30

2m+3s=75

Explanation:

let m be the no of multiple choice questions and s be the short questions then there are a total of 30 questions

m+s=30------A

there are 2 points for m(multiple choice questions) and 3 points for short questions (s) and totalling to 75

2m+ 3s=75
