A) \[\frac{9}{40}\]and \[\frac{31}{41}\]
B) \[\frac{13}{50}\]and \[\frac{264}{350}\]
C) \[\frac{63}{250}\]and \[\frac{187}{250}\]
D) None of these
Correct Answer: C
Solution :
\[\frac{1}{4}=0.25\]and \[\frac{3}{4}=0.75\] \[\frac{9}{40}=0.225,\frac{31}{40}=0.775\](No), \[\frac{13}{50}=0.26,\frac{264}{350}=0.754\](No) \[\frac{63}{250}=\frac{63\times 4}{1000}=\frac{252}{1000}=252,\frac{187}{250}=\frac{187\times 4}{250\times 4}\]\[=\frac{748}{1000}=7.48\] Clearly, \[\frac{63}{250}\]and \[\frac{187}{250}\]lies between \[\frac{1}{4}\]and \[\frac{3}{4}.\]
