Age difference between kushi and shyam??

As far as i know Arnav is 27, kushi is 20 (if she lost the parents same day as arnav lost ) becuse at that time she was 7 and arnav was 14, but anjali was possibly 20 at that time., so tecniclly anjai is 6 year older than arnav and shyam might be equal or elder than anjali so now anjali is 33 and shyam may be 33 or more bascically the age difference between shaym and kushi is almost 13 or more years oh god??? shyam is really a sick man ...who is obsessed for a gal who is 13 yr younger than him...oh god this men is really jerk...he himself looks dirty???
