NIMCET 2020 — Reasoning PYQ

Step 1: Decode the given statement

The problem provides the expression:

$$\text{Sachin * Madan - Reena}$$

Let's break it down into two logical sections according to the given rules:

1. $\text{Sachin <em> Madan}$ Using rule i ($A</em>B⟹A=B$):

   $$\text{Sachin}=\text{Madan}$$

   (Sachin and Madan are exactly the same age)

2. $\text{Madan - Reena}$

   Using rule ii (A - B \implies B &lt; A, meaning $B$ is younger than $A$):

   \text{Reena} &lt; \text{Madan}

   (Reena is younger than Madan)

Step 2: Combine the relationships

Now, let's combine both parts into a single chronological sequence:

\text{Reena} &lt; \text{Sachin} = \text{Madan}

From this arrangement, we can draw the following conclusions:

• Sachin and Madan are the oldest (and share the same age).

• Reena is younger than both Sachin and Madan.

• Therefore, Reena is the youngest among them.

Step 3: Evaluate the options

• A) Reena is youngest: Correct, as established by our inequality relationship.

• B) Reena is oldest: Incorrect, she is the youngest.

• C) Madan is younger than Reena: Incorrect, Madan is older than Reena.

• D) Madan is the youngest: Incorrect, Madan is one of the oldest.

Correct Option: A
