Growth Fund investment is of Rs 581.25 and Units alloted are 30.337 at the rate of 19.16 as on 18/12/2008
so the total investment is of (581.28 + 581.25 = 1162.53 ) so out of Rs 1499.94 your actual investment is of only Rs 1162.53 and the remaining Rs 337.44 which is almost 22.5% of total investment has gone for various charges such as admin charges mortality charges etc.
