Question

CUET PG 2022 — Mathematics PYQ

CUET PG | Mathematics | 2022

The arithmetic means of two observations is 125 and their geometric means is 60. Find the harmonic mean of the two observations.

Choose the correct answer:

Explanation

Given:

Arithmetic Mean ( $A$ ) = $125$

Geometric Mean ( $G$ ) = $60$

Formula:

Hum jaante hain ki Arithmetic, Geometric aur Harmonic mean ke beech ka sambandh (relationship) yeh hota hai:

G^2 = AH

Step-by-step Solution:

Is formula se hum $H$ ki value nikaal sakte hain:

H = \frac{G^2}{A}

Values ko substitute karne par:

H = \frac{(60)^2}{125}

H = \frac{3600}{125}

Ab isse simplify karte hain:

H = \frac{720}{25}

H = \frac{144}{5}

Final Answer:

H = 28.8
