A Correct answer
Explanation

Brother = 0.25 * Father. Brother = Naresh - 8. Brother = Mother - 32. Mother = Father - 16. Let Father = F. Brother = 0.25F. Mother = 0.25F + 32. Also Mother = F - 16. So 0.25F + 32 = F - 16. 48 = 0.75F. F = 64. Mother = 64 - 16 = 48. After 5 years, Mother = 48 + 5 = 53.
