A) 8
B) 10
C) 12
D) 16
Correct Answer: B
Solution :
We have \[{{M}_{1}}=10,\] \[{{W}_{1}}=\frac{2}{5},\,\,{{D}_{1}}=8\] \[{{M}_{2}}=?,\,{{W}_{2}}=\frac{3}{5},\,\,{{D}_{2}}=12\] \[\therefore \] \[{{M}_{1}}{{D}_{1}}{{W}_{2}}={{M}_{2}}{{D}_{2}}{{W}_{1}}\] \[\Rightarrow \] \[10\times 8\times \frac{3}{5}={{M}_{2}}=12\times \frac{2}{5}\] \[\therefore \] \[{{M}_{2}}=10\]
