Answer 2

Answer:

(A) 3:5

Step-by-step explanation:

x:y = 2:1

We know that,

Product of extremes= Product of means.

→ x * 1 = y * 2

→ x = 2y

y = 1

According to the question,

${x}^{2} - {y}^{2} : {x}^{2} + {y}^{2} \\→ {2y}^{2} - {y}^{2} : {2y}^{2} + {y}^{2} \\ → {(2 \times 1)}^{2} - {1}^{2} : {(2 \times 1)}^{2} + {1}^{2} \\ → {2}^{2} - {1}^{2} : {2}^{2} + {1}^{2} \\ →4 - 1 : 4 + 1 \\ →3:5$

Therefore,

x²-y²:x²+y² = 3:5.

-------------------------------------------------

If you think this process is tough then,

x:y = 2:1

→ x = 1 , y = 2

According to the question,

x² - y² : x² + y²

→ 2²-1² : 2² + 1²

→ 4 - 1 : 4 +1

→ 3 : 5

Therefore,

x²-y² : x² + y² = 3:5.
