It seems that CV teams of PR are confused about the leap years. Is it 18 yrs or 20yrs? Some times Manav says 18 yrs but when Teju mentioned that her age is 20 yrs. Teju, Ovi, Arjun, and Purvi should be no more than 19yrs old because when they left for Canada when they were born. It seems that the writers are confused and they do not know what the past history was. What do you think?
