Giả sử số nu \(A=15\%N\)
\(\Rightarrow L=\dfrac{3,4.N}{2}=2550\left(\overset{o}{A}\right)\)
\(\Rightarrow\left\{{}\begin{matrix}A=T=15\%N=225\left(nu\right)\\G=X=35\%N=525\left(nu\right)\end{matrix}\right.\)
\(\Rightarrow H=2A+3G=2025\left(lk\right)\)
Giá sử số nu \(G=15\%N\)
\(\Rightarrow\left\{{}\begin{matrix}G=X=15\%N=225\left(nu\right)\\A=T=35\%N=525\left(nu\right)\end{matrix}\right.\)
\(\Rightarrow H=2A+3G=1725\left(lk\right)\)
