For the present study we have investigated the distribution of solar flares in the northern and southern hemispheres of the sun which are associated with coronal mass ejections (CMEs) during the period 2005 to 2010. The period of our investigation includes the descending phase of solar cycle 23 and ascending phase of solar cycle 24. Our analysis indicates that 31.14% of solar flares associated with CMEs are obtained in the northern hemisphere whereas 68.86% are in the southern hemisphere which clearly indicates the dominance of the southern hemisphere and asymmetry between the northern and southern hemispheres during 2005 to 2010. We also found 66.31% B-class, 24.87% C-class, 7.55% M-class and 1.17% X-class solar flares in association with CMEs by our rigorous study and temporal analysis of data.
