Vidya got her son exactly two years after her marriage (D). Vipin was born in January (E) and, since no couple was married in January (A), Vipin is not Vidya’s son. Also, as Moneesh was born within sixteen months of his parents wedding (F), he too is not Vidya’s son. Since Kiran got married six months after Radha (B), either Radha was married in February and Kiran in August, or Radha married in March and Kiran in September (A). All children were born more than a year after their parents' weddings (C). As Moneesh was born within sixteen months of his parents wedding but not between August and January, both inclusive (F), he cannot be Kiran's son because she was married either in August or in September (deduced above). Hence, Moneesh, who is neither Vidya's son nor Kiran's must be Radha's son. It follows that Vipin is Kiran’s son. Since Kiran got her child within sixteen months of her marriage (D), and Vipin is January born (E), she must have got married in September. Therefore, Radha was married in March (B) and is Mohan’s wife (A) Hence, Moneesh’s parents are Mohan and Radha.
