    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 :

    \[\sqrt{6}=2.44,\,\sqrt{5}=2.33,\sqrt{3}=1.73\] \[a=\sqrt{6}-\sqrt{5}=0.21\] \[b=\sqrt{5}-2=0.23\] \[c=2-\sqrt{3}=0.27\]
