Answer:
It depends on how much money Ahmad has saved.
Step-by-step explanation:
If he has a small amount of money, the best he can do is to put his savings on a safe investment, like treasury bonds, an ETF, or a safe and low risk bond of a trustworthy company.
If Ahmad has a larger amount of money, he can put his savings in riskier assets like stock, which could give him a higher return. He could also create a more diverse investment portfolio, with some of his savings going to safer, lower yield investment instruments, and the rest going to riskier, higher yield investment instruments.
