P and Q started a business and invested for the same time. If the ratio of their investment is 4 : 5, then, their profit is also in the ratio of 4 : 5. Is this statement true?
Yes
In a partnership business, if the capital of each partner is invested for the same period of time, then the profit or loss is distributed according to their invested capital.
Hence, as both of them invested for the same time and the ratio of their investment is 4 : 5, their profit is also in the ratio of 4 : 5.
