Sashi is 2 year elder than Sunita, Sunita is 3 year elder than Bindu, Shekhar is 1 year elder than Bindu. Who is the youngest in the group?

According to the question,
Lakshmi is elder than Meenu
Lakshmi > Meenu
Leela is elder than Meenu but younger than Lakshmi
Lakshmi > Leela > Meenu

Let the age of Shyam = x year
Then, age of Ram = 2x year
