Calculating the frequency of output

I was given this question:

A farm has purchased a star connected 3 ph emergency generator running at 1000 rpm which has 6 poles with a total flux per pole of 0.022Wb. If the stator has a total of 72 slots with 4 conductors in each slot, determine
i. The frequency of the output

I have answered it:

P = 6/2 = 3
F= NP/60 = 1000 x 3/ 60 =50Hz

But I have been told that I have got the wrong flux value can somebody tell me where I have gone wrong??

The flux value should not come into this part of the question ...

And it hasn't in your calculation , which appears correct to me.
