Using BB events recorded in the Belle detector, the charge averaged branching fractions for B→π+π-, K+π-, K+π0, K0π0 were measured with statistically significant signals. The results confirm that B(B0→K+π-) is larger than B(B0→π+π-), and indicate that B(B+→h+π0) and B(B0→K0π0) seem to be larger than expected in relation to the B0→h+π- and B+→K0π+ modes based on isospin or penguin dominance arguments.
