A) 4
B) 6
C) 8
D) 10
Correct Answer: B
Solution :
Let two numbers are a and b. Geometric mean\[=\sqrt{ab}\] \[\Rightarrow \] \[12=\sqrt{ab}\] \[\Rightarrow \] \[ab=144\] ...(i) and harmonic mean\[=\frac{2ab}{a+b}\] \[\Rightarrow \] \[\frac{48}{5}=\frac{2ab}{a+b}\] [From Eqs. (i)] \[\Rightarrow \] \[(a+b)=30\] ...(ii) On solving Eqs. (i) and (ii), we get\[a=6,\text{ }b=24\]You need to login to perform this action.
