A) \[\frac{N}{5}\]
B) \[\frac{N}{10}\]
C) \[\frac{N}{20}\]
D) \[\frac{N}{40}\]
E) \[\frac{N}{25}\]
Correct Answer: D
Solution :
\[NV={{N}_{1}}{{V}_{1}}+{{N}_{2}}{{V}_{2}}+{{N}_{3}}{{V}_{3}}\] or, \[1000N=1\times 5+\frac{1}{2}\times 20+\frac{1}{3}\times 30\]or \[N=\frac{1}{40}\].You need to login to perform this action.
