This is a very simple ratio (shown in percentage) that represents how your overall portfolio (across all goals) is split into equity funds and debt funds.
For example, If 20% of my overall portfolio of investments is in equity funds and 80% of the portfolio is in debt funds, then this ratio will simple show as 20% : 80%
Compare it with your recommended risk profile and ensure that you have not taken more risk (more risk means higher equity exposure than what your risk profile indicates). E.g for moderate risk profile, your equity exposure should not exceed 60%. If you invest as per your risk profile in all the goals, this will usually not be the case.
