Answer:

6.86 kg

Explanation:

Here ,apparently the weight and number of sheets are proportional.

Let m be the weight of 700 sheets.


\text{} \begin{matrix}500\ \text{sheets} \text{} \longrightarrow 4.9\ \text{kg} \\ 700\ \text{sheets} \text{} \longrightarrow m\ \text{kg} \end{matrix}

coefficient of proportionality :


\text{} \text{The coefficient of proportionality is equal to :} \ (700)/(500) =(7)/(5)

Then


(m)/(4.9) = (7)/(5)

Then


m = (7)/(5) * 4.9 =6.86 \ \text{kg}
