Question

In the test,(+5) marks are for every correct answer. Lakshmi gets 45 correct and 15 incorrect answer. What is her score?

Answer 1

Answer:

Marks given for one correct answer = 5

So, marks given for 10 correct answers

= 5 X 10 = 50

Lakshmi's score = 30

Marks obtained for incorrect answer

= 30- 50 = -20

Marks given for one incorrect answer

= (-2)

Therefore, number of incorrect answers

= (−20)÷(−2)=10
