Correct Answer: 9 : 1
Solution : Given: The sum of two numbers is 25 and their difference is 20. Let $n_1,$ and $n_2$ be the two numbers. $n_1= \frac{\text{Sum + Difference}}{2}=\frac{25+20}{2}$ = $\frac{45}{2}$ $n_2 = \frac{\text{Sum – Difference}}{2}=\frac{25-20}{2}$ = $\frac{5}{2}$ So, the required ratio = $\frac{45}{2}:\frac{5}{2}$ = 9 : 1 Hence, the correct answer is 9 : 1.
