Answer 2

Answer:

option b is correct one

Explanation:

we need to have the numbers lying between $\frac{1}{10} and \frac{9}{4}$,

$\frac{1}{10}$=0.10 and $\frac{9}{4}$=2.25.

in option a $\frac{21}{20} =1.05 ,\frac{1}{4} =0.25 , \frac{3}{80} =0.0375$

here, 0.0375<0.10<0.25<1.05<2.25

in option b $\frac{1}{2} =0.5,\frac{15}{19} =0.79,\frac{11}{5} =0.73$

here, 0.10<0.5<0.73<0.79<2.25

therefore option b is right.

in option c $\frac{17}{6} =2.83,\frac{19}{20} =0.95,\frac{53}{4} =13.25$

here,0.10<0.95<2.25 <2.83<13.25

in option d $\frac{49}{25} =1.96,\frac{17}{4} =4.25,\frac{2}{3} =0.67$

0.10<0.67<1.96<2.25 <4.25

Therefore option b is the answer.
