The average marks scored by Ram in 5 tests of Physics is 30. How many marks must he obtain in his next test to make the average 32?

42

The average marks scored by Ram in 5 tests of Physics = 30

So the total marks of 5 subjects = 30 × 5 = 150

According to the question,

The new average must be = 32

So the subject will be = 6

Now the total marks will be = 32 × 6 = 192

So he need to obtain = 192 - 150 = 42 marks in the new subject.
