​

Answer 1

Answer:

402.5

average=observation

$\div$

number of observations=5

average=80.5

80.5=total marks

$\div$

5

80.5

$\times$

5=402.5

Answer 2

let 100 be the maximum marks of each subject

let marks scored by him =y

y/500×100=80.5

y×100=80.5×500

y=80.5×500/100

y=80.5×5

y=402.5

so,total marks scored by him = 402.5
