Ans: I would like to suggest that in spite of putting all your eggs in one basket (that is, debt funds), you should go for diversification of funds for goods returns.

You should put 50 per cent of your investment in debt funds, and 50 per cent should go into balanced funds which is combination of debt and equity. This way you will always have 65 per cent of investment in debt only and 35 per cent in equity.

Some good debt funds can be:

1. ICICI Prudential Ultra Short Term Fund - Direct Plan - Daily IDCW Payout

2. Aditya Birla Sun Life CEF - Global Agri Plan - Growth-Direct Plan

3. IDFC Government Securities Fund - Constant Maturity Regular - Growth

4. Nippon India Gilt Securities Fund - Direct Plan Defined Maturity Date Option - Growth

Some Good balanced funds can be:

1. HDFC Balanced Advantage Fund

2. ICICI Prudential Balanced Advantage Fund

3. Nippon India Balanced Advantage Fund

4. Edelweiss Balanced Advantage Fund.

5. L&T Dynamic Equity Fund.

Ans: For, achieving this target your thought process is correct. This target can surely be achieved in the next 15 years. By taking an average CAGR 14 per cent annualised, which is currently the average return in last 15 years given Indian growth-based mutual funds, this target is surely achievable. Seeing India's bright future ahead in terms of economic growth, the best mutual funds for this aim will be growth-based stock mutual funds.

Ans: Provided a little time frame and a huge target of education of your twins, we have very limited scope left. You should invest all these funds on monthly basis in growth oriented mutual funds. Indian growth-based mutual funds have a history of giving 14 per cent -16 per cent of CAGR annualised returns, and seeing the bright prospects of Indian economy probability is high that it will continue. This will give enough returns for starting the education of your twins for first 2-3 years. Further for higher education I will suggest you to keep this investment going in the same way till they end their graduation, which will give enough funds to keep their higher education in line.

Ans: It is wrong to say that it cannot be done by top ups in current SIPs; it can be done. But it is never a good investment method of going for top ups. Let the current portfolio go as it is going and see your money go up gradually. For growing your money quickly, I will suggest to find new upcoming NFOs in good AMCs and start a fresh long term portfolio in growth-based equity mutual fund that will achieve your targets.

Ans: Nice to know that you can invest 10 lakh in lump sum. I will suggest you to invest this lump sum money in debt-based mutual funds which can give inflation-beating return. You should try to keep in line with returns on this fund and wait for a right opportunity to invest this fund in balanced or growth funds (like when you see market crash).

Further as far as your monthly investment goes you should invest the same in balanced funds which will be a mixture of debt and equity and will give a good return with safety of funds.

Some good balanced funds can be:

1. HDFC Balanced Advantage Fund

2. ICICI Prudential Balanced Advantage Fund

3. Nippon India Balanced Advantage Fund

4. Edelweiss Balanced Advantage Fund.

5. L&T Dynamic Equity Fund.
