pH = 12 means it is a base. So when you dilute that it remains a base. the concentration decreases.
pOH = 14 -12 = 2
so [ OH ]^- = 10^-2 / mole
after dilution = [ OH^- ] = 10^-5 /mole
so new pOH = 5
so pH = 14 - 5 = 9
pOH = 14 -12 = 2
so [ OH ]^- = 10^-2 / mole
after dilution = [ OH^- ] = 10^-5 /mole
so new pOH = 5
so pH = 14 - 5 = 9

pH = 12
therefore,
[H+] = 10-12
it is diluted 1000 times, therefore,
[H+] = 10-12 * 103
[H+] = 10-9
therefore,
pH = -log[H+]
= 9
