The mark of the 11th Candidate must be 50 because you need to find the total mark which is 22*45 and deduct (10*50)+(11*40). =990-(500+440)
=990-940
=50 marks

Answer:
A
Explanation:
Total marks scored by 22 candidates =22×45=990
Total marks scored by first 10 candidates =10×55=550
Total marks scored by last 11 candidates =11×40=440
∴ Marks scored by 11th candidatte =990−(550+440)=0
