Question

Guys if you can answer this I'll love you forever I need to get a hundred on this test.

Kelsey got a 74% on her Social Studies test. The test had 50 questions. How many
questions did she NOT answer correctly?

Answer 1

Let total correct number of questions she answered be x.

She got 74% in her test.

According to the question:.

100 × x/50 = 74

100x / 50 = 74

2x = 74

x = 37

Questions she didn't answer correctly = total questions - questions she answered correctly

=> 50 - 37

=> 13

So, She answered 13 questions incorrectly.

Answer 2

Answer:

percentage he got not =100-74= 26. Therefore , required answer=26/100 ×50=13
