    What is the unitary method?

    The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
    We have been given that bertha has 6 daughters and no sons.
    And some of her daughters have 6 daughters, and the rest have none. bertha has a total of 30 daughters and granddaughters and no great-granddaughters.
    Therefore, the total daughter + grandaughter = 30
    The given daughter of Betha = 6
    The grand daughter = 30-6 ; 24
    then 24 /6 = 4
    4 have 6 daughters each
    Since 2 of Bertha’s daughters have no daughters and all of the granddaughters also don’t have daughters
    so
    2+24 = 26
    Hence, There are 26 bertha’s daughters and granddaughters have no daughters.
