    Let a \[=\sqrt{6}-\,\sqrt{5},\,b=\sqrt{5}-\,2,\,c=2-\,\sqrt{3.}\] Then point out the correct alternative among the four alternatives given below.

    A) \[a<b<c\]         

    B)         \[b<a<c\]

    C) \[a<c<b\]                     

    D)  \[b<c<a;\]

    Correct Answer: A

    Solution :

    [a] \[\sqrt{6}=2.44,\,\,\sqrt{5}=2.23,\,\,\sqrt{3}=1.73\] \[a=\sqrt{6}-\,\sqrt{5}=0.21\] \[b=\sqrt{5}-\,2=0.23\] \[c=2-\,\sqrt{3}=0.27\]
