Your agent is saying that if you invest Rs. 50000 pa for 20yrs in HDFC Pension Super, you will get 70,00,000/- (This will happen, ONLY If the return on your investment is 14.11%, compounded yearly for all 20 years.)That is impossible.

See the past 5 years absolute return on HDFC Pension Super - Growth Fund II is just 2.18%.

Whether this fund would give 14.11% every year in future, only God knows?
