What is the number of scores possible in a 150 questions CAT paper, where 1/3
mark is deducted for every wrong answer and 1 mark is awarded for every
correct answer?

Consider it n = +3 for right and -1 for wrong
Max possible: 150*3 = 450
Min possible: 150*(-1) = -150
Total range: 450 - (-150) + 1 = 601
Max possible: 150*3 = 450
Min possible: 150*(-1) = -150
Total range: 450 - (-150) + 1 = 601
So, every score at interval of 1/3 is possible, except the 150 - 1/3 , 150 - 2/3 , 149 - 2/3
3 scores not possible..
Answer = 601-3 = 598
Please correct me if i am wrong

Integral thode hi pucha hai...Just calculate taking +3 and -1 as usual...same hi to cases banenge, be it +3 or +1

Nai bhai..not necessarily integer scores..and moreover not every question has to be attempted Ans is 598

Not necessary..-1/3 for a negative score matlab it can even be a non integer value IMO

Max score = 150
Min score = -50
Total possible scores = ((150-(-50)) * 3) -3+1)= 598?
Min score = -50
Total possible scores = ((150-(-50)) * 3) -3+1)= 598?
Probability that I hit a target is 1/2. The target is destroyed if 3 shots hit the target. What is the minimum number of shots that I should try, so that the probability that I destroy the target is more than 0.9 ?
1) 6
2) 7
3) 8
4) 9
