A) \[47.603\]
B) \[4.7603\]
C) \[147.6003\]
D) \[47.6003\]
Correct Answer: C
Solution :
\[63.9805=6\times 10+3\times 1+9\times \frac{1}{10}\] \[+8\times \frac{1}{100}+5\times \frac{1}{10000}\] \[\therefore \] \[A=10,\,B=1,\,C=\frac{1}{10},\,D=100,\,E=\frac{1}{10000}\] \[\therefore \] \[4A+7B+6C+D+3E\] \[=4\times 10+7\times 1+6\times \frac{1}{10}+100+3\times \frac{1}{10000}\] \[=4+7+0.6+100+0.0003=147.6003\]
