The present study is aimed at finding out the effect of variation of the initial mass function (IMF) on star-formation efficiency (SFE) in clouds of various masses. Using the model of Elmegreen and Clemans (1985), it is found that the star-formation efficiency depends on the IMF, and, if the slope of the IMF is steeper, rich clusters with relatively high SFEs will be formed. Steeper mass function also favors the formation of bound clusters. The results obtained in the present work also explain the concentration of the oldest clusters in the outer disk of the Galaxy, and the increasing trend in the average total mass of clusters with age is suggested by Pandey et al. (1989).
