Explanation

Seven years ago, Aniruddh:Bhavna = 7:9, so A-7 : B-7 = 7:9. Chandranshu is 12 years older than Aniruddh (C = A + 12) and 12 years younger than Bhavna (C = B - 12). This means B - A = 24. From the ratio: (A-7)/(B-7) = 7/9. Substituting B = A+24: (A-7)/(A+17) = 7/9. Cross-multiplying: 9A-63 = 7A+119. So 2A = 182, A = 91. Therefore C = 91 + 12 = 103 years.
