i think so not sure!

Thank u

Answer 2

Explanation:

Answer = 67.5 gf

Applied the method of straight line method

Take two points A(5,80) and B(40,10)

First find the slope=(10-80)/(40-5)=-2

x-5=-2(y-80)

Now put the value of x=30 get output y

30-5=-2(y-80)

y-80=-25/2

y=80-12.5

y=67.5gf

So final answer is 67.5gf weight of a metre scale balanced at 30 cm mark.
