The age of Ram is double that of Shyam and half the of Sohan. Shyam is older than Mohan. Who is the oldest?

Suppose the age of Shyam = P years According to question , Age of Ram = 2 × age of Shyam = 2P years Age of Sohan = 4 × age of Shyam = 4P years ∴ Shyam > Mohan So, Sohan (4P) > Ram (2P) > Shyam (P) > Mohan ∴ Sohan is the oldest.
