Question

In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. In three of the four pairs, the same pattern is applied and hence they form a group. Select the number-pair that DOES NOT belong to this group.

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 - Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Question (English)

In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. In three of the four pairs, the same pattern is applied and hence they form a group. Select the number-pair that DOES NOT belong to this group.

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 - Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

  1. 335 - 119
  2. 358 - 152 ✓ Correct
  3. 317 - 101
  4. 308 - 92
Explanation:

Logic: Check the difference between the two numbers in each pair.

  • Option 1: $335 - 119 = 216$
  • Option 2: $358 - 152 = 206$
  • Option 3: $317 - 101 = 216$
  • Option 4: $308 - 92 = 216$

Conclusion: In options 1, 3, and 4, the difference between the numbers is consistently $216$ (which is $6^3$). However, in Option 2, the difference is $206$. Thus, Option 2 is the odd one out.

प्रश्न (हिंदी)

निम्नलिखित संख्या-युग्मों में, दूसरी संख्या पहली संख्या पर निश्चित गणितीय संक्रियाएँ करके प्राप्त की जाती है। चार में से तीन युग्मों में एक ही पैटर्न का पालन किया गया है और इसलिए वे एक समूह बनाते हैं। उस संख्या-युग्म का चयन करें जो इस समूह से संबंधित नहीं है।

(नोट: संक्रियाएं पूर्ण संख्याओं पर ही की जानी चाहिए, न कि अंकों को अलग-अलग करके। उदाहरण के लिए, 13 पर संक्रियाएं (जैसे जोड़ना/घटाना/गुणा करना) पूरी संख्या 13 पर की जानी चाहिए। 13 को 1 और 3 में तोड़कर उन पर संक्रियाएं करने की अनुमति नहीं है।)

  1. 335 - 119
  2. 358 - 152
  3. 317 - 101
  4. 308 - 92
स्पष्टीकरण:

तर्क: प्रत्येक युग्म में दी गई संख्याओं के बीच के अंतर (difference) की जाँच करें।

  • विकल्प 1: $335 - 119 = 216$
  • विकल्प 2: $358 - 152 = 206$
  • विकल्प 3: $317 - 101 = 216$
  • विकल्प 4: $308 - 92 = 216$

निष्कर्ष: विकल्प 1, 3 और 4 में, संख्याओं के बीच का अंतर $216$ है (जो $6^3$ है)। हालाँकि, विकल्प 2 में, अंतर $206$ है। इसलिए, विकल्प 2 समूह से अलग (odd one out) है।
