  1. Let a = √6 - √5, b = √5 - 2, c = 2 - √3 Then point out the correct alternative among the four alternatives given below.
    1. a < b < c
    2. b < a < c
    3. a < c < b
    4. b < c < a;
Correct Option: A

We know that , √6 = 2.44, √5 = 2.23, √3 = 1.73
a = √6 - √5 = 2.44 - 2.23 = 0.21
b = √5 - 2 = 2.23 - 2 = 0.23
c = 2 - √3 = 2 - 1.73 = 0.27
