In cros cannizzaro reaction we get mixtureof products n?and plz tell that if p methoxy benzaldehyde is stable by+i effect of och3then howoh- can attackon it

Electrophilicity of para methoxy benzaldehyde is less due to +I effect. But it is still electrophilic. So nucleophile will react but just tha reation will be a little slow.

yes para methoxy benzaldehyde is slightly less electrophilic. it doesn't mean that nucleophile will not attack.
