Q 1.what do u mean by risk and return in financial management?

Answer 1

The principle that potential return rises with an increase in risk. Low levels of uncertainty (low risk) are associated with low potential returns, whereas high levels of uncertainty (high risk) are associated with high potential returns. In other words, the risk-return tradeoff says that invested money can render higher profits only if it is subject to the possibility of being lost.

Because of the risk-return tradeoff, you must be aware of your personal risk tolerance when choosing investments for your portfolio. Taking on some risk is the price of achieving returns; therefore, if you want to make money, you can't cut out all risk. The goal instead is to find an appropriate balance - one that generates some profit, but still allows you to sleep at night.

Answer 2

Risk and return are what they imply to be.
Risk is the probability of success or failure.
Return is the payment receivable for taking such a risk.
If return sounds tempting enough and desireable / beneficial enough to take the risk of losing the principal, then it is probably a worthwhile chance gamble, but certainly not garanteed.
The one constant in the universe, scientifically speaking, is that everything is contantly changing. Wealthy people predict these changes and adapt to go with the flow, or at least adapt once the change is observed. If your business is working at going with the general trend of adaptive flow of society, then it will likely be profitable, unless some other factor not accounted for changes.
