Type z question - confused
Duncan is twice as old as Sebastian will be next year. Isabella is 8.
Sebastian is three years older than Isabella was last year.
How many years old is Duncan?
My answer
Last year Isabella was 7
So Sebastian is 10
Next year he will be 11
So Duncan is 22
I was seeing some old posts and apparently 22 is not the right answer - right answer is 20 - Please can someone help me with this one ? ( I believe it is from an IPS paper )
