Question

$1.$ There is a group of five persons $A,B,C,D$ and $E.$
$2.$ One of them is a horticulturist, one is a physicist, one is a journalist, one is an industrialist and one is an advocate.
$3.$ Three of them $A,C$ and advocate prefer tea to coffee and two of them $B$ and the journalist prefer coffee to tea.
$4.$ The industrialist and $D$ and $A,$ are friends to one another but two of them prefer coffee to tea.
$5.$ The horticulturist is $C^{\prime }s$ brother.

Who is the horticulturist?

• A. $A$
• B. $B$
• C. $C$
• D. $D$

Answer 1

The correct option is A $A$

$A$ prefers tea. So, from $\left(4\right)$, the industrialist and $D$ prefer coffee.
From $\left(3\right)$, $B$ and the journalist prefer coffee. So, $B$ is the industrialist and $D$ is the journalist.
Now $A,C$ and advocate remain.
Clearly, $E$ is the advocate.
The horticulturist is $C^{\prime }s$ brother. It can be only $A$. So, $C$ is a physicist.
We have
$A\to$ Horticulturist $\to$ Tea
$B\to$ Industrialist $\to$ Coffee
$C\to$ Physicist $\to$ Tea
$D\to$ Journalist $\to$ Coffee
$E\to$ Advocate $\to$ Tea
