Divya and Raveena can do a work alone exactly in 20 and 25 days respectively.

However, when they work together, they do 25% more work than is expected. If they work for a few days alone and for few days together (both being integers only), then the

work could not have been completed in exactly

A. 10 days

B 14 days

C. 16 days

D. 17 days

E. either none or at least 2 of these
