A) \[\frac{67}{25}\]
B) 15
C) \[\frac{128}{11}\]
D) \[\frac{128}{99}\]
Correct Answer: B
Solution :
Required value \[=\frac{16}{3}\div \frac{11}{9}\times \frac{1}{4}\left( 10+\frac{3}{1-1/5} \right)\] \[=\frac{16}{3}\div \frac{11}{9}\times \frac{1}{4}\left( 10+\frac{3}{4/5} \right)\]\[=\frac{16}{3}\div \frac{11}{9}\times \frac{1}{4}\left( 10+\frac{15}{4} \right)\] \[=\frac{16}{3}\div \frac{11}{9}\times \frac{1}{4}\times \frac{55}{4}\] \[=\frac{16}{3}\div \frac{9}{11}\times \frac{1}{4}\times \frac{55}{4}\] \[=15\]
