Correct answer: C. 102, 255, 306
Explanation
Let the numbers be 2x, 5x and 6x. Then 2x + 5x + 6x = 13x = 663, so x = 51. The numbers are 2 × 51 = 102, 5 × 51 = 255 and 6 × 51 = 306. Note that option 1 also adds up to 663 but is not in the ratio 2 : 5 : 6. Hence the answer is 102, 255, 306.मान लीजिए संख्याएँ 2x, 5x और 6x हैं। तब 2x + 5x + 6x = 13x = 663, अतः x = 51। संख्याएँ हैं 2 × 51 = 102, 5 × 51 = 255 और 6 × 51 = 306। ध्यान दें कि विकल्प 1 का योग भी 663 है, किंतु वह 2 : 5 : 6 के अनुपात में नहीं है। अतः उत्तर 102, 255, 306 है।More Mathematical Reasoning and Aptitude questions
