Question

Sunil obtained average 75 marks in 4 subjects. He obtained 65 marks in the fifth subject. Find the average marks obtained by him.

Answer 1

Answer:

73

Step-by-step explanation:

Sunil obtained an average 75 marks out of 100

he archived it in 4 subjects

i.e. 75×4=300(total marks in 4 subjects)

now he gets 65 in 5th subject

thus 300+65=365 in 5 subjects

average marks = total marks / number of subjects

=365/5

=73

So his average in 5 subjects is 73.
