how/what should be the query for this result

I have 1 table "Progress"

P_no b_no status build_date

25             1                First_slab        2006/4/5
25              1               second slab     2006/5/6
25              2                first slab          2006/1/2
25              2                third slab     2006/2/3

o/p should be as
Pno,bno, status, max(build_date)

sample o/p can be as below

25              1               second slab     2006/5/6
25              2               third slab        2006/2/3
