On which of the following dates, Constituent Assembly of India adopted the National Flag?
- (a)22 January, 1950
- (b)24 January, 1950
- (c)22 July, 1947
- (d)22 July, 1948
Correct — C, 22 July 1947. The Constituent Assembly of India adopted the National Flag — the horizontal tricolour of saffron, white and green with the navy-blue Ashoka Chakra at its centre — on 22 July 1947, just about three weeks before Independence on 15 August 1947. The resolution was moved by Jawaharlal Nehru; the design retained the earlier Swaraj (Congress) flag's colours but replaced the spinning wheel (charkha) with the 24-spoke Ashoka Chakra (Dharma Chakra).
- (a)22 January, 1950 — Wrong — no national symbol was adopted on this date; it is a near-miss trap clustered around the January 1950 dates (the Constitution came into force on 26 January 1950).
- (b)24 January, 1950 — Wrong — this is the date the Constituent Assembly adopted the National Anthem ('Jana Gana Mana') and National Song ('Vande Mataram'), and members signed the Constitution — not the flag.
- (d)22 July, 1948 — Wrong year — the correct day (22 July) is paired with the wrong year; the flag was adopted in 1947, before Independence, not 1948.
India's National Flag was adopted by the Constituent Assembly on 22 July 1947. It is a horizontal tricolour — saffron (top), white (middle) and India-green (bottom) in equal proportion, with a 24-spoke navy-blue Ashoka Chakra in the centre of the white band. The width-to-length ratio is 2:3. The design was based on Pingali Venkayya's Swaraj flag, with the charkha replaced by the Dharma Chakra from the Sarnath Lion Capital.
The trap is a cluster of Independence-era dates. Separate the two milestones: the FLAG was adopted on 22 July 1947 (before Independence), whereas the NATIONAL ANTHEM and National Song were adopted on 24 January 1950. Anchoring '22 July 1947 = flag' rules out both the 1950 options and the wrong-year 1948 option.
- National Flag adopted by the Constituent Assembly on 22 July 1947
- Design proposed on the basis of Pingali Venkayya's Swaraj flag; charkha replaced by the Ashoka Chakra
- Ashoka Chakra has 24 spokes; flag ratio is 2:3 (width:length)
- By contrast, the National Anthem and Song were adopted on 24 January 1950

- Confusing the flag date (22 July 1947) with the anthem/song date (24 January 1950)
- Picking the right day but the wrong year (22 July 1948)
UPPSC/UPSC ask this as a date recall, or test the flag's ratio (2:3), the 24 spokes of the Ashoka Chakra, or the Flag Code — keep the flag firmly at 22 July 1947.
What is the number of spokes in the Dharmachakra in the National Flag of India?
- (a) 16
- (b) 18
- (c) 22
- (d) 24

- (a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
- (b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
- (c) Statement-I is correct but Statement-II is incorrect
