A class consists of 50 students. 16 students take French and got an average mark of 74 out of 100. 21

students take Hindi and got an average mark of 72 out of 100. The rest of the students take Sanskrit and got

an average mark of 76 out of 100. What is the class average mark for language?

Answer 1

Answer:

73.68

Step-by-step explanation:

french marks = 16*74=1184

hindi marks = 21*72=1512

sanskrit students = 50-16-21=13

sanskrit marks = 13*76=988

total marks received =1184+1512+988=3684

average marks = 3684/50= 73.68
