Gọi 2 số đó là a và b
Ta có : \(\frac{a}{b}=\frac{7}{12}\)
\(\frac{a+10}{b}=\frac{3}{4}\Rightarrow\frac{a}{b}+\frac{10}{b}=\frac{3}{4}\Rightarrow\frac{10}{b}=\frac{3}{4}-\frac{a}{b}=\frac{3}{4}-\frac{7}{12}=\frac{1}{6}\)
\(\Rightarrow b=10:\frac{1}{6}=60\)
\(\Rightarrow a=\frac{7}{12}.b=\frac{7}{12}.60=35\)
Vậy tổng 2 số là : 60 + 35 = 95
