⚠️ Exam Traps & High-Yield Points

#	Wrong belief	Correct fact
1	"Rajiv Gandhi was assassinated while PM"	Rajiv Gandhi was assassinated on 21 May 1991 during the election campaign, not while serving as PM. He had lost power in 1989.
2	"Morarji Desai was the first Gujarati PM"	Correct, but note: he was also the first non-Congress PM and the oldest PM at oath (age 81). Both are more commonly tested.
3	"Charan Singh was the shortest-serving PM"	His full tenure was ~170 days (not shortest). He only attended Parliament for 23 days before resigning. Vajpayee's 1996 tenure (13 days) was shorter.
4	"LPG reforms were initiated by Manmohan Singh as PM"	LPG reforms were initiated by PM P.V. Narasimha Rao; Manmohan Singh was the Finance Minister who executed them (1991).
5	"The Deputy PM position is in the Constitution"	There is no constitutional provision for Deputy PM — it is a political/administrative convention
6	"There is a minimum age to become PM"	No specific age is required for PM (unlike President — 35 years). The PM must be a member of Parliament, which requires age 25 (LS) or 30 (RS).
7	"Manmohan Singh was Finance Minister under Narasimha Rao as PM"	Correct — and Rao himself held the External Affairs portfolio at times. Manmohan Singh's role as FM is a commonly tested link.
8	"IK Gujral never sat in Lok Sabha"	Correct — IK Gujral was a Rajya Sabha member throughout his political career; never contested Lok Sabha. Manmohan Singh was similar.
9	"Vajpayee's 13-day government fell on a no-confidence vote"	The 1996 (13-day) government ended by resignation before facing a vote. It was Vajpayee's 1999 (2nd term) government that lost a no-confidence motion — by just ONE vote (270–269), 17 April 1999.
10	"The PM holds office for 5 years"	The PM holds office at the pleasure of the President (Art. 75(2)) — as long as they command majority in Lok Sabha. There is no fixed term.
11	"India has had 14 Prime Ministers"	India has had 14 individuals serve as PM. But if counting sequential appointments (including Nanda's two acting stints, Indira's two terms, Vajpayee's three terms, Modi's three terms), the count is higher. Narendra Modi is the 14th individual PM.
