Question

A science exam was conducted using three sets of papers. there were 534 papers in the first set, 642 papers in the second set, and 632 papers in the third set. If 16 teachers are to correct all the papers, hoe many papers can each correct if divided equally?

Answer 1

Answer:

Given that:

Total number of people n(S)=642

No. of peoples having high school certificate n(E)=514

P(E)=Probability that the person has a school certificate

∴P(E)=

n(S)

n(E)

=

642

514

=0.8006

Answer 2

First, we have to count the total number of sheets.

$534 + 642 + 632 = 1808$

Now, we have to divide the total number of sheets by the total number of teachers.

$\frac{1808}{16} = 113 \: answer$
