Answer:

Let the number of weight produced by an extension of 21cm be 'x'

Weight -- 250 x

extension-- 3.5 cm 21cm

Varies directly

250*10/35 = x/21

250*10*21/35 = x

1500cm = x

\begin{gathered}so \: therefore \: the \: number \: of \\ weight \: produced \: by \: an \\ extension \: of \: 12cm \:is \\ 1500\end{gathered}
