Let R = gS – 4, when S = 8 and R = 16. If S = 10, then R is equal to · ABC26GN0953

Putting S = 8 and R = 16, we have: $R = gS - 4 \Rightarrow 16 = 8g - 4 \Rightarrow 8g = 20 \Rightarrow g = \frac{20}{8} = \frac{5}{2}$. When S = 10, $R = gS - 4 \Rightarrow R = \frac{5}{2} \times 10 - 4 = 25 - 4 = 21$.
