As per your income, you are under-insurance. Look for term insurance plans from Aegon Religare & ICICI Prudential. They offer very low premium on their online term insurance policy.
I hope you understand the various charges under these plans like premium allocation charges, policy admin charges etc.
Also, please note that pension in India is taxable. So, you need to pay tax whenever you start getting pension.
I would recommend to invest in equity diversified mutual funds for better returns.
Hope it will help you.
