Question

Item 56

Answer 1

Answer:

a 25 questions, 4 points   b 19 questions

Step-by-step explanation:

a 96:100 = 24 : x

x = (100 x 24)/96 = 25 questions

100 : 25 = 4 points

b 76:100 = x : 25

x = (76 x 25)/100 = 19 questions

Answer 2

Answer:

Question 1:

There are 25 questions on the test.

Each question is worth 4 marks each.

Question 2:

Your friend answered 19 questions correctly

Step-by-step explanation:

Question 1:

question answered = 24

percent earned = 96%

total number of points = 100%

$\frac{questions answered }{percentage earned}$ x 100

$\frac{24}{96}$ x 100 ⇒ 0.25 x 100 ⇒ 25

there are 25 questions on the test

$\frac{100}{25} = 4$

each question is 4 marks each

Question 2:

percent earned by your friend = 76%

(percent earned by your friend x total number of question) ÷ 100

76 x 25 ÷ 100

1900 ÷ 100

= 19
