Answer 1

$\huge\boxed{Answer}$

Firstly , For a Class

Sum of the test scores of p students

= x ( let)

Average = x/p

70 = x/p

p = x/70

Next , For another class -

Sum of the test scores of same test of

n students = y (let)

average = y/n

n = y/92

Sum of the test scores of both class

students = (70p + 92n)

Now , (70p + 92n)/(p + n) = 86

70p + 92n = 86p + 86n

6n = 16p

16p = 6n

p/n = 6/16

p/n = 3/8

Answer 2

ANS IS 3/8.
