Hello, i had a query
While calculating ways to achieve 0, the min number of correct question would be 1C+3W which would leave 96 unattempted question. 4 would go 24 times + 1 for the first case. How is the answer 26 here and not 25?
Thanks in advance
Possibly you have not considered the case of 0 C 0 W 100 U? Someone who just went and got paralysed in the paper and attempted nothing would also get a 0…
