RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
Amalgam
Reasoning for Odd Word Selection
The question requires identifying the word that does not belong with the others based on a common characteristic.
Identifying Word Properties
- Tin: A chemical element (symbol Sn), classified as a metal.
- Gallium: A chemical element (symbol Ga), classified as a metal.
- Titanium: A chemical element (symbol Ti), classified as a metal.
- Amalgam: A mixture or alloy of mercury with another metal. It is not a distinct chemical element.
Determining the Different Word
Tin, Gallium, and Titanium are all individual chemical elements, specifically metals. Amalgam, however, is an alloy or compound that includes mercury, distinguishing it from the other options which are pure elements.
Therefore, Amalgam is the odd word out.
