Giúp mình vs

Answer 1

\(N=\dfrac{5100}{3,4}.2=3000\) nu

Ta có: \(\left\{{}\begin{matrix}A.G=6\%\\A+G=50\%\end{matrix}\right.\) và A < G

\(\Rightarrow\left\{{}\begin{matrix}A=T=20\%\\G=X=30\%\end{matrix}\right.\)

\(A_1=15\%N_1,\%A=\dfrac{\%A_1+\%A_2}{2}=>A_2=25\%N_2\)

=> \(A_1=T_2=225,A_2=T_1=375\)

Tương tự \(X_2=20\%N_2=>X_1=40\%N_1\)

=> \(X_2=G_1=300,X_1=G_2=600\)
