A) \[\frac{N}{5}\]
B) \[\frac{N}{10}\]
C) \[\frac{N}{20}\]
D) \[\frac{N}{40}\]
Correct Answer: D
Solution :
\[NV={{N}_{1}}{{V}_{1}}+{{N}_{2}}{{V}_{2}}+{{N}_{3}}{{V}_{3}}\] \[1000\,\,N=1\times 5+\frac{1}{2}\times 20\,\,+\frac{1}{3}\times 30 or\,\,N=\frac{1}{40}\]You need to login to perform this action.
