### Question 1

The sum of two numbers is 53. Their difference is 19. They are in the ratio?

**A**

$2{2/17}$.

**B**

$3{5/16}$.

**C**

1.

**D**

$4{11/19}$.

**Soln.**

**Ans: a**

Let the numbers be a and b, and let their ratio be k such that $a/b = k$. We are given $a + b = 53$ ⇒ $b(k + 1) = 53$. Similarly, from the difference we can obtain $b(k - 1) = 19$. Dividing we get ${k + 1}/{k - 1} = 53/19$. By componendo and dividendo, $k = {53 + 19}/{53 - 19}$ = ${36/17}$, which is same as: $2{2/17}$.
