Minky is 6 years older than Pinky. Pinky is 8 years younger than Rinky. Rinky is 4 years older than Vinky. Vinky is 9 years younger than Kinky. Who is the second eldest?

Option 2 : Rinky

Let's denote the names of the people by their initial letters.

According to the given information:

1) Minky is 6 years older than Pinky → M > P.
Therefore, Minky = Pinky + 6

2) Pinky is 8 years younger than Rinky → P < R.
Therefore, Rinky = Pinky + 8

From 1 and 2, Minky < Rinky
Therefore, Rinky – Minky = 2

3) Rinky is 4 years older than Vinky. → R > V.
Therefore, Rinky = Vinky + 4

4) Vinky is 9 years younger than Kinky → K > V
Therefore, Kinky = Vinky + 9

Minky + 2 = Vinky + 4

Therefore, Vinky = Minky - 2 or Minky = Vinky + 2

Thus, Kinky > Rinky > Minky > Vinky > Pinky
Hence, Rinky is the second eldest among all others.
