How about Yeye ni rais wa arobaini na tatu au wa arobaini na nne?
that's more correct, really
But still counted as incorrect (reported again, Jun '19)
I included 'Je...' and was marked wrong. Reported it on 4/28/20
Or start with je to indicate a question. Plus I wonder how necessary yeye is
It is. Usually you exclude it when the verb has the subject prefix, but since the verb is 'ni' you include it, since you don't have any other way to identify the subject
