### Question

If $x/2 = y/19 = z/28$, then ${x + y + z}/x$ = ?

**A**

$24{1/2}$.

**B**

$25{1/2}$.

**C**

$23{1/2}$.

**D**

$13{3/4}$.

**Soln.**

**Ans: a**

Let $x/2 = y/19 = z/28$ = k. Then ${x + y + z}/x$ is same as ${2k + 19k + 28k}/{2k}$ which equals $24{1/2}$.

${49/2}$ is same as $24{1/2}$.
