A) \[\frac{2}{7},\frac{20}{7},\frac{10}{7}\]
B) \[\frac{15}{7},\frac{20}{7},\frac{3}{7}\]
C) \[\frac{10}{7},\frac{15}{7},\frac{2}{7}\]
D) \[\frac{20}{7},\frac{5}{7},\frac{15}{7}\]
Correct Answer: D
Solution :
From \[x=\frac{{{m}_{1}}{{x}_{2}}+{{m}_{2}}{{x}_{1}}}{{{m}_{1}}+{{m}_{2}}},\,\,y=\frac{{{m}_{1}}{{y}_{2}}+{{m}_{2}}{{y}_{1}}}{{{m}_{1}}+{{m}_{2}}}\], \[z=\frac{{{m}_{1}}{{z}_{2}}+{{m}_{2}}{{z}_{1}}}{{{m}_{1}}+{{m}_{2}}}\]; \[x=\frac{20}{7},\,\,y=\frac{5}{7},\,\,z=\frac{15}{7}.\]You need to login to perform this action.
