If x = √8 - √7, y = √6 - √5 and z = √10 - 3, which of the following is true ?

Correct Answer: z < x < y

Explanation:

x = √8 - √7 = 1/(√8 + √7) and y = √6 - √5 = 1/(√6 + √5) and z = √10 - 3 = 1/(√10 + 3)


As (√8 + √7) > (√6 + √5), (√8 - √7) < (√6 - √5)


As (√10 + 3) > (√8 + √7) > (√6 + √5)


z < x < y.
