All the calculations Should be done on the basis of the present year 2021.

Jenny's age is a prime number. The difference between Jenny and Jessica's age is a prime number. The sum of Jerry and Juhi's age is a perfect square, whereas Juhi is younger. The age of Jasmine is a multiple of 5 but her age is not a perfect square. Only one person is there in between Joseph and Jonny who was not born in any even year. The difference between Jimmy and Jessica's age is a multiple of 7.
