Question

In a test (+4) marks are given for every correct answer and (-2) marks are given for every incorrect answer. Sai answered all the questions and scored 26 marks from 8 correct answers. How many incorrect answers had Sai attempted ?​

Answer 1

Answer:

Incorrect answers = 3

Step-by-step explanation:

Lets assume X is the correct answer and Y is the incorrect answer so

Sai answered all the questions and scored 26 marks from 8 correct answers i.e.

8*4 - 2*Y = 26

32 - 2Y = 26

-2Y = -6

Y = 3

So incorrect answers attempted = 3
