    The wingspans of different species of birds is given below.
    Species of birds Blue jay Golden eagle Seagull Albatross
    Length of wingspans \[\frac{41}{100}m\] \[2\frac{1}{2}m\] \[1\frac{7}{10}m\] \[3\frac{3}{5}m\]
    How much longer is the wingspan of a Golden eagle than the wingspan of a Blue jay?

    A)  \[\frac{209}{100}cm\]                      

    B)         \[\frac{209}{100}m\]

    C)         \[\frac{9}{100}m\]                

    D)         \[\frac{215}{100}cm\]          

    Correct Answer: B

    Solution :

    Wingspan of Blue jay\[\text{=}\frac{41}{100}m\] Wingspan of Golden eagle \[=2\frac{1}{2}m=\frac{5}{2}m\] Wingspan of a Golden eagle is longer than wingspan of Blue jay by \[\left( \frac{5}{2}-\frac{41}{100} \right)m=\left( \frac{250-41}{100} \right)m=\frac{209}{100}m\]
