If x = 5√5, y = 7 + √5 and z = 2 + 4√5, then which of the following is correct?

A x > y > z

B x > z > y

C y > x > z

D z > x > y

E None

Solution

Correct Answer: Option B

দেওয়া আছে,
x = 5√5
= 5 × 2.236
≈ 11.18

y = 7 + √5
= 7 + 2.236
≈ 9.236

z = 2 + 4√5
= 2 + 4 × 2.236
= 2 + 8.944
≈ 10.944

এখন মানগুলি সাজিয়ে পাই,
x ≈ 11.18
y ≈ 9.236
z ≈ 10.944
সুতরাং, x > z > y
