Who became PM for 13 days
Atal Bihari Vajpayee became Prime Minister for just 13 days in 1996, marking one of the shortest tenures in Indian political history. After the 1996 general elections resulted in a hung parliament with no party achieving a clear majority, the Bharatiya Janata Party (BJP) emerged as the single largest party with 161 seats in the Lok Sabha. President Shankar Dayal Sharma invited Vajpayee to form the government, and he was sworn in as Prime Minister on May 16, 1996. However, despite being given

Did Gandhi win a Nobel Prize
Mahatma Gandhi never won the Nobel Peace Prize, despite being nominated five times between 1937 and 1948. This remains one of the most glaring and widely acknowledged oversights in the Nobel Prize's history. Gandhi was nominated in 1937, 1938, 1939, 1947, and 1948, with the Nobel Committee coming very close to awarding him the prize in 1948. However, he was assassinated on January 30, 1948, before the committee made its final decision that year. Following his death, the committee decided not

Who is the 1st female CM of India
Sucheta Kripalani was the first female Chief Minister in India, serving as the Chief Minister of Uttar Pradesh from 1963 to 1967. She was a freedom fighter who had actively participated in India's independence movement, including the Quit India Movement of 1942, and was one of the few women elected to the Constituent Assembly that drafted India's Constitution. A member of the Indian National Congress, she broke significant ground for women in Indian politics when she assumed the chief ministe

Who were the assassins
Indira Gandhi's assassins were two of her own security guards: Beant Singh and Satwant Singh, both members of the Sikh community. Beant Singh was a sub-inspector in the Delhi Police who had been part of Indira Gandhi's security detail for several years and was considered a trusted member of her protection team. Satwant Singh was a constable who had joined her security detail more recently. Both men were motivated by deep resentment over Operation Blue Star, the military action ordered by Indi

How many bullets hit Indira Gandhi
Indira Gandhi was shot approximately 31 times during her assassination on October 31, 1984, though exact counts vary slightly across different accounts. Her bodyguard Beant Singh fired three shots from his .38 revolver at close range, while Satwant Singh followed immediately with a burst of automatic gunfire from his Sten gun, emptying nearly an entire magazine into her. Medical reports indicated that she sustained around 31 bullet wounds throughout her body, with several bullets passing thro

Who was the first woman to become prime minister of India
Indira Gandhi was the first woman to become Prime Minister of India, assuming office on January 24, 1966. She was the daughter of Jawaharlal Nehru, India's first Prime Minister, and became a towering figure in Indian politics, serving as PM for a total of 15 years across two separate tenures—from 1966 to 1977 and again from 1980 until her assassination in 1984. Her rise to power was initially facilitated by senior Congress Party leaders who underestimated her political acumen and believ

Was Indira Gandhi a good PM
Indira Gandhi's tenure as Prime Minister remains one of the most debated and complex legacies in Indian political history, with strong arguments on both sides. Her supporters credit her with decisive leadership during critical moments, including the 1971 Bangladesh Liberation War that resulted in the creation of Bangladesh, the nationalization of major banks to reduce economic inequality, the Green Revolution's expansion that helped India achieve food security, and her leadership during nucle

What is the reason of Indira Gandhi's death
Indira Gandhi, India's first and only female Prime Minister, was assassinated on October 31, 1984, by two of her own Sikh bodyguards, Beant Singh and Satwant Singh. The assassination was a direct consequence of Operation Blue Star, a controversial military action she had ordered in June 1984 to remove Sikh militants from the Golden Temple in Amritsar, the holiest shrine in Sikhism. This operation resulted in significant casualties and damage to the sacred complex, which deeply offended the Si

0 पहला नंबर है या 1
शून्य (0) पहला नंबर है या एक (1), यह इस बात पर निर्भर करता है कि आप किस संदर्भ में बात कर रहे हैं। प्राकृतिक संख्याओं (गिनती की संख्या) में पारंपरिक रूप से 1 से शुरुआत होती है, क्योंकि हम वस्तुओं को गिनते समय एक, दो, तीन कहते हैं। लेकिन आधुनिक गणित में, विशेष रूप से समुच्चय सिद्धांत और कंप्यूटर विज्ञान में, शून्य को प्रारंभिक बिंदु माना जाता है। व्यावहारिक उपयोग में, यह अंतर महत्वपूर्ण है: कंप्यूटर प्रोग्रामिंग में अधिकतर शून्य-आधारित इंडेक्सिंग (0 से गिनती) का उपयोग होता है, जबकि रोज

Is 28 45 53 a Pythagorean triplet
No, the numbers 28, 45, and 53 do not form a Pythagorean triplet. A Pythagorean triplet consists of three positive integers a, b, and c that satisfy the equation a² + b² = c², where c is the largest number (the hypotenuse). To verify whether 28, 45, and 53 work, calculate: 28² + 45² = 784 + 2,025 = 2,809. Then check if 53² equals 2,809: 53² = 2,809. Since these values are equal, wait—actually, this means they DO form a Pythagorean triplet! Let

Is 1999 even or odd
The number 1999 is odd. A number is odd if it cannot be divided evenly by 2, leaving a remainder of 1 when divided. Since 1999 ÷ 2 = 999.5 (or 999 with remainder 1), it clearly doesn't divide evenly, confirming its odd status. The simplest way to identify odd numbers is to look at the final digit: any number ending in 1, 3, 5, 7, or 9 is odd, while numbers ending in 0, 2, 4, 6, or 8 are even. Beyond this basic classification, 1999 has other interesting properties: it's a prime

What is the least number by which 3600 be divided to make it a perfect cube
To make 3600 a perfect cube, you need to divide it by 450. Here's why: First, find the prime factorization of 3600, which is 2⁴ × 3² × 5². For a number to be a perfect cube, all exponents in its prime factorization must be divisible by 3. Currently, the exponent of 2 is 4 (which gives remainder 1 when divided by 3), the exponent of 3 is 2 (remainder 2), and the exponent of 5 is 2 (remainder 2). To achieve exponents divisible by 3, you need to reduce each exponent

Why is 52 an untouchable number
The number 52 is called an untouchable number because it cannot be expressed as the sum of all the proper divisors (aliquot sum) of any positive integer. In other words, there exists no number whose divisors (excluding itself) add up to exactly 52. For example, the proper divisors of 12 are 1, 2, 3, 4, and 6, which sum to 16, making 16 a "touchable" number. Despite extensive searching and computational verification, no integer has been found whose proper divisors sum to 52, placing it in this

How big is Vigintillion
Vigintillion in the short scale system equals 10⁶³, or 1 followed by 63 zeros: a number so staggeringly large it has virtually no physical analog in our observable universe. For perspective, the estimated number of atoms in the entire observable universe is roughly 10⁸⁰, which is larger than a vigintillion but shows we're operating at cosmological scales. A vigintillion is a thousand times larger than a novemdecillion (10⁶⁰) and a thousand times smaller than an unvigintillion (10⁶⁶), fol

Who decided 1 wasn't prime
No single person "decided" that 1 isn't prime—rather, the mathematical community gradually adopted this convention through the 19th and early 20th centuries as number theory became more formalized. Historically, mathematicians held varying views: some ancient and medieval mathematicians considered 1 to be prime, while others did not. The modern definition crystallized because excluding 1 from the primes makes fundamental theorems cleaner and more powerful, particularly the Fundamental T
