A) 30
B) 40
C) 50
D) 60
Correct Answer: B
Solution :
\[{{M}_{1}}=10,\] \[{{D}_{1}}=8,\] \[{{W}_{1}}=20\] and \[{{M}_{2}}=x(let),\] \[{{D}_{2}}=10,\] \[{{W}_{2}}=100\] \[\therefore \] \[\frac{{{M}_{1}}{{D}_{1}}}{{{W}_{1}}}=\frac{{{M}_{2}}{{D}_{2}}}{{{W}_{2}}}\] \[\therefore \] \[\frac{10\times 8}{20}=\frac{x\times 10}{100}\] \[\Rightarrow \] \[x=8\times 5=40\]You need to login to perform this action.
