Download Solution PDFx అనేది 12.8 మరియు 64.8 మధ్య సగటు అనుపాతం అయితే మరియు y అనేది 38.4 మరియు 57.6కి మూడవ అనుపాతం అయితే, 2x : y దీనికి సమానం:
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFx 12.8 మరియు 64.8 మధ్య సగటు అనుపాతం అయితే, అప్పుడు
12.8 : x : : x : 64.8
⇒ 12.8/x = x/64.8
⇒ x 2 = 12.8 × 64.8
⇒ x = √[16 × 0.8 × 0.8 × 81]
⇒ x = 4 × 0.8 × 9
y అనేది 38.4 మరియు 57.6కి మూడవ అనుపాతం అయితే, అప్పుడు
38.4 : 57.6 : : 57.6 : వై
⇒ 38.4/57.6 = 57.6/y
⇒ y = (57.6 × 57.6)/38.4
⇒ y = 86.4
ఇప్పుడు,
2x : y = 2 × 4 × 0.8 × 9 : 86.4 = 2 : 3
చిన్న ట్రిక్:
మీన్ ప్రొపోర్షనల్ x = √12.8 × 64.8 = 28.8
మూడవ అనుపాత y = (57.6 × 57.6)/38.4 = 86.4
ఇప్పుడు,
2x : y = 2 × 28.8 : 86.4 = 2 : 3Last updated on Jun 13, 2025
