All she is telling you is that 5 days of the week make her thirty.
you are trying to find out what it would be if you counted the other 2 days of the week as well.
all you know is that five sevenths of her true age is 30.
Given that you want to calculate the full age i.e. seven sevenths.
if 5 sevenths is 30
1 seventh is 6 i.e. thirty divided by 5
and seven sevenths, the whole age 6 x 7 is 42.
