A couple up or a number of

[Dibya]

Dear all, which one of the two sentences is more suitable?
1)We have incurred a couple of losses in our business.
2)We have incurred a number of losses in our business.
Thanks a lot.

They might both be suitable. What context do you have in mind? What do you mean by 'losses'?

There are more (X)s in "a number of Xs" than in "a couple of Xs".
