A) 20
B) 24
C) 30
D) 33
Correct Answer: B
Solution :
Using the formula, \[\frac{{{M}_{1}}{{D}_{1}}{{H}_{1}}}{{{W}_{1}}}\,=\frac{{{M}_{2}}{{D}_{2}}{{H}_{2}}}{{{W}_{2}}}\] Let \[{{W}_{1}}=x\] and \[{{W}_{2}}=3x\]. \[{{M}_{1}}=16,\,\,{{H}_{1}}=12,\,{{D}_{1}}=8\] \[{{H}_{2}}=8,\,{{D}_{2}}=24\] \[\therefore \,\,\frac{16\times 8\times 12}{x}=\frac{{{M}_{2}}\times 24\times 8}{3x}\] \[\Rightarrow \,{{M}_{2}}=24\].
