Answer» Let the broken pieces out of 12 be x ⇒ The Glass not broken = (12 - x) Ratio of Unbroken : Broken = x : (12 - x) ⇒ Now For x = 1 ⇒ Ratio = 1 : 11 ⇒ Now For x = 2 ⇒ Ratio = 2 : 10 = 1 : 5 ⇒ Now For x = 3 ⇒ Ratio = 3 : 9 = 1 : 3 ⇒ Now For x = 4 ⇒ Ratio = 4 : 8 = 1 : 2 ⇒ Now For x = 5 ⇒ Ratio = 5 : 7 ⇒ Now For x = 6 ⇒ Ratio = 6 : 6 = 1 : 1 ⇒ Now For x = 7 ⇒ Ratio = 7 : 5 ⇒ Now For x = 8 ⇒ Ratio = 8 : 4 = 2 : 1 ⇒ Now For x = 9 ⇒ Ratio = 9 : 3 = 3 : 1 ⇒ Now For x = 10 ⇒ Ratio = 10 : 2 = 5 : 1 ⇒ Now For x = 11 ⇒ Ratio = 11 : 1 Clearly on comparing various ratios we FIND that ratio which is not POSSIBLE is 3 : 2 |
