Parents have money to invest, need advice on safe long term allocation

Hey everyone, I’m 22F and fairly new to investing. I’ve been investing for about a year now, mostly in ETFs tracking major indices. I recently found out that my parents have some cash they want to invest: * \~₹35 lakhs in my mom’s account * \~₹20 lakhs in my dad’s account This is essentially their life’s savings, so I want to be *very careful* with it. My biggest concern is inflation eating away the value if the money just sits in savings accounts or low-interest FDs. Some context: * My dad will retire in \~2 years and is already a senior citizen. He will receive a pension, so regular expenses are covered. * My mom will continue working. * They don’t need this money immediately, the goal is long term growth (15–20 years). * Risk tolerance is moderate. I’m thinking mostly “safe” equity rather than aggressive investing. * Since my dad is a senior citizen, government-backed schemes or bonds offering higher interest rates would also be a good option for the debt portion. I’m looking for guidance on: 1. What kind of **asset allocation** would make sense here? * % in Equity * % in FDs / debt instruments * % in gold/silver or other assets 2. Any **government schemes / bonds / senior-citizen options** worth considering. 3. Any **mutual funds / ETFs / SIP ideas** suitable for parents (Indian markets). 4. Whether lump sum investing or staggered SIP/STP would be better given current market levels. I understand that I shouldn’t blindly copy advice, but I’d really appreciate learning how people would *think through* a situation like this. Thanks a lot in advance!
