well....its futile to expect so much accuracy regarding age in ektaa's serial.
anywy, as far as i know....DM once said he got married to subhadra at age of 27 and if hiten was born soon after then DM must be 50-51 because hiten is 23.
subhi died i think 7-8 years back (i think this was also mentioned some time back), i think subhi died after giving birth to suraj.
motiben cannot be that young wen she had maulik....because she is older than DM. DM got married at 27 and then he had hiten, kaddu and then the third child. 27 itself is not young age. maulik is 19. so wen maulik was born DM was 31 and so motiben must hv been in her early 30s. how can a woman who is hving her first child in her 30s be called very young i really dont know.
