A) \[\frac{7}{15}\]
B) \[\frac{9}{15}\]
C) \[\frac{6}{15}\]
D) \[\frac{8}{15}\]
Correct Answer: D
Solution :
We have, \[\frac{2}{15}+\frac{4}{15}+\frac{5}{15}=\frac{11}{15},\] \[\frac{1}{15}+\frac{5}{15}+\frac{5}{15}=\frac{11}{15}\] And \[\frac{1}{15}+?\bigcirc+\frac{2}{15}=\frac{11}{15}\]or, \[\frac{1}{15}+\frac{8}{15}+\frac{2}{15}=\frac{11}{15}\] \[\therefore ?\bigcirc =\frac{8}{15}\]
