**A**

$2{3/5}$.

**B**

$4{1/2}$.

**C**

$1{1/7}$.

**D**

4.

**Soln.**

**Ans: a**

Let the numbers be a and b, and let their ratio be k such that $a/b = k$. We are given $a + b = 18$ ⇒ $b(k + 1) = 18$. Similarly, from the difference we can obtain $b(k - 1) = 8$. Dividing we get ${k + 1}/{k - 1} = 18/8$. By componendo and dividendo, $k = {18 + 8}/{18 - 8}$ = ${13/5}$, which is same as: $2{3/5}$.
