Firlakuza [10]

Lesly got 14 answers correctly.

Let the correct answers be C.

Let the incorrect answers be I.

Given the following data:

Total number of questions = 30 questions.

Ratio of C to I = 7 : 8

C to I = 7 + 8 = 15

To find the number of answers she got correctly;

$C = \frac{7}{15}$ × $30$

$C = 7$ × $2$

Correct answers, C = 14 answers
