Given that the ratio of two quantities is 2 to 5, say the two quantities are 2x and 5x. Thus, after an increase of 3, we get that the new quantities are (2x + 3) and (5x + 3).

Thus, the new ratio is (2x + 3)/(5x + 3).

We cannot get the unique value of the ratio. Thus, the correct answer is Option E.

The correct answer: E

Hope this helps!

We can let 2x and 5x be the two original quantities. Therefore, the ratio of the two new quantities is (2x + 3) / (5x + 3). However, since x can be any (positive) value, there is no way we can determine the new ratio.

Answer: E
