Find the odd one out from the given alternatives:
- (a)Bhagat Singh
- (b)Chandrashekhar Azad
- (c)Rajguru
- (d)Manmohan Singh
Answer
Why
Correct — D.
Rule: find the field the other three names share.
Bhagat Singh, Chandrashekhar Azad and Rajguru were revolutionaries of the freedom struggle, all members of the Hindustan Socialist Republican Association (HSRA), and all three had died by March 1931.
Manmohan Singh was an economist and Prime Minister of India from 2004 to 2014 → option (d).
Why the others are wrong
- (a)Bhagat Singh — Bhagat Singh was an HSRA revolutionary, hanged in Lahore on 23 March 1931 with Rajguru and Sukhdev. He belongs with Azad and Rajguru, not apart from them.
- (b)Chandrashekhar Azad — Chandrashekhar Azad led the HSRA and died at Alfred Park, Allahabad, in February 1931 when surrounded by police. He is one of the three revolutionaries.
- (c)Rajguru — Rajguru was hanged with Bhagat Singh and Sukhdev in Lahore on 23 March 1931. An HSRA member like Bhagat Singh and Azad, he fits the group.
Concept
An odd-one-out on people asks for the category three of them share. Here it is revolutionary freedom fighters of the 1920s, linked through the HSRA.
Manmohan Singh was born in 1932, after all three had died. He made his name in economics and government, not in the independence movement.
Nothing in the names themselves separates the four: the surname Singh appears in options (a) and (d). The grouping comes from what each person is known for.
Key facts
- Bhagat Singh, Chandrashekhar Azad and Rajguru were members of the Hindustan Socialist Republican Association (HSRA).
- Bhagat Singh, Rajguru and Sukhdev were hanged in Lahore Central Jail on 23 March 1931.
