You can invest the one lakh into two funds just to diversify your investment. Go for a large cap fund (value based) and one multicap fund that is growth oriented.
Invest only in direct plans. ₹ One lakh at 15% can get you ₹ 1.33 crores over 35 years, whereas a regular plan of same fund from a broker gets you just ₹ 84 lakhs due to a 1.5% annual commission. So that is a ₹ 50 lakh difference!
Couple of funds to consider are Quantum Long Term Value Fund and ICICI Prudential Value Discovery Fund. But for the best selection, do check out Jama.co.in
