Download Solution PDFகொடுக்கப்பட்ட தகவல்:
A : B = 7 : 8
B : C = 7 : 9
கருத்து:
N என்பது a : b ஆல் வகுக்கப்பட்டால்,
முதல் கூற்று = N × a/(a + b)
இரண்டாம் கூற்று = N × b/(a + b)
கணக்கீடு:
A/B = 7/8 ----(i)
Also B/C = 7/9 ----(ii)
சமன்பாடுகளை பெருக்கும் போது
⇒ (A/B) × (B/C) = (7/8) × (7/9)
⇒ A/C = 49/72
∵ A : B = 49 : 56
∴ A : B : C = 49 : 56 : 72
Alternate Method
A : B = 7 : 8 = 49 : 56
B : C = 7 : 9 = 56 : 72
⇒ A : B : C = 49 : 56 : 72
