संख्या a और b का अनुपात = 3 : 7 है
गणना:
माना अनुपात x है
तो, संख्या a और b क्रमशः 3x और 7x हैं।
प्रश्नानुसार,
⇒ (3x + 9)/(7x + 9) = 9/17
⇒ 17 × (3x + 9) = 9 × (7x + 9)
⇒ 51x + 153 = 63x + 81
⇒ 51x - 63x = 81 - 153
⇒ -12x = -72
⇒ x = 6
इसलिए, a = 3x = 3 × 6 = 18
⇒ b = 7x = 7 × 6 = 42
∴ संख्या a और b 18 और 42 हैं
