29295 ways a candidate can attempt the questions if A question paper consists of three sections 4,5 and 6 questions respectively. and Attempting one question from each section is compulsory
Step-by-step explanation:
A question paper consists of three sections 4,5 and 6 questions respectively
Attempting one question from each section is compulsory
Numbers of ways 4 Questions can be attempted = 2⁴ = 16
but attempting 0 questions is not allowed
Hence 2⁴ - 1 = 15 ways
Similarly for section with 5 Question = 2⁵ - 1 = 31 ways
Similarly for section with 6 Question = 2⁶ - 1 = 63 ways
Total number of ways = 15 * 31 * 63
= 29295
