Question

In an examination consisting of 100 questions, one mark is given for every correct answer and one-fourth mark is deducted for every wrong answer. A candidate attempts all the 100 questions and scores a total of 70 marks. Find the number of questions he marked correctly. (a) 66 (b) 76 (c) 86 (d) 82

Answer 1

Answer:

it is 66 only i cant give explanation

Answer 2

Answer:

Right answer is Option b) 76

because,

if we consider 76 right answers,

then wrong answers = 100 - 76 = 24

and know that 1/4 marks are deducted for every wrong answer.

so, 24/4 = 6        

76 - 6 = 70

so, 76 is right answer.

Sorry i don't know the exact explanation.

but 76 is the right answer
