Show answer & explanation
Correct answer: A
Let the ages of the two brothers be 4x and 3x years, based on the ratio 4:3.
The difference in their ages is 4x - 3x = x years.
Given that the elder brother is 6 years older, so x = 6.
Therefore, the ages are 4 × 6 = 24 years and 3 × 6 = 18 years.
हिन्दी उत्तर:
माना दोनों भाइयों की आयु क्रमशः 4x और 3x वर्ष है, जो 4:3 के अनुपात के अनुसार है।
उनकी आयु का अंतर 4x - 3x = x वर्ष है।
दिया गया है कि बड़ा भाई 6 वर्ष बड़ा है, इसलिए x = 6।
इसलिए, आयु 4 × 6 = 24 वर्ष और 3 × 6 = 18 वर्ष हैं।
