### Question 1

15 times the middle of three consecutive even numbers is 150 more than 11 times the smallest of the three numbers. What is the middle number?

### Question 2

The sum of two numbers is 39. Their difference is 21. They are in the ratio?

**A**

$3{1/3}$.

**B**

$6{1/2}$.

**C**

$2{1/3}$.

**D**

$3{4/5}$.

**Soln.**

**Ans: a**

Let the numbers be a and b, and let their ratio be k such that $a/b = k$. We are given $a + b = 39$ ⇒ $b(k + 1) = 39$. Similarly, from the difference we can obtain $b(k - 1) = 21$. Dividing we get ${k + 1}/{k - 1} = 39/21$. By componendo and dividendo, $k = {39 + 21}/{39 - 21}$ = ${10/3}$, which is same as: $3{1/3}$.
