42
Question Author
that's what we thought, but could you tell me how you came to that answer please?
she is only counting 5 days of the week instead of 7 so 30 is 5/7.
1/7 will be 6
and 7/7 will be 42.

i appreciate your answer but i don't get how we count it as 42, without first knowing that she's 42!

do you know what i mean?
she says here age is 30 if you dont count weekends.
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.
