दिया है:

प्रारंभिक अनुपात = 5 ∶ 6

अंतिम अनुपात 17 ∶ 22 से कम होना चाहिए

गणना:

मान लीजिए कि घटाने के लिए आवश्यक न्यूनतम पूर्ण संख्या a है।

प्रश्नानुसार,

(5 - a)/(6 - a) < 17/22

⇒ 5 × 22 - 22a < 17 × 6 - 17a 

⇒ 110 - 22a < 102 - 17a 

⇒ 110 - 102 < - 17a + 22a 

⇒ 8 < 5a 

⇒ 8/5 = 1.6 < a 

∴ सबसे छोटी पूर्णांक संख्या 2 होनी चाहिए।
