The National Flag, known as the 'Tiranga', has three horizontal bands of Saffron, White, and Green. The ratio of the length of the flag to its width is 3:23:2.

•

The Ashoka Chakra in the center of the National Flag is navy blue and contains 2424 spokes, symbolizing the 2424 hours of the day and constant movement.

•

The National Anthem, 'Jana Gana Mana', was composed by Rabindranath Tagore and takes approximately 5252 seconds to perform in its full version.

•

The National Emblem is an adaptation of the Lion Capital of Ashoka at Sarnath. It features the motto 'Satyameva Jayate' (Truth Alone Triumphs) inscribed in Devanagari script at the base.

•

National Monuments like the Taj Mahal are preserved as heritage. The Taj Mahal is famous for its perfect bilateral symmetry, where the left half is a mirror image of the right half.

•

The National Calendar is based on the Saka Era, with Chaitra as its first month and a normal year of 365365 days.

📐Formulae

Ratio of National Flag=LengthWidth=32\text{Ratio of National Flag} = \frac{\text{Length}}{\text{Width}} = \frac{3}{2}

Duration of National Anthem≈52 seconds\text{Duration of National Anthem} \approx 52 \text{ seconds}

Number of Spokes in Ashoka Chakra=24\text{Number of Spokes in Ashoka Chakra} = 24

💡Examples

Problem 1:

If a designer is making a large National Flag for a stadium and the length is decided to be 1212 meters, what should the width be to maintain the official ratio?

Solution:

The official ratio is 3:23:2. Given Length (LL) = 12 m12 \text{ m}. Width=23×L\text{Width} = \frac{2}{3} \times L Width=23×12=8 m\text{Width} = \frac{2}{3} \times 12 = 8 \text{ m}

Explanation:

Since the ratio of length to width is 3:23:2, the width must be two-thirds of the length to follow the legal specifications of the Indian Flag.

Problem 2:

Calculate how many years have passed since India adopted its National Constitution (January 26, 1950) up to the year 2024.

Solution:

2024−195074\begin{array}{r} 2024 \\ -1950 \\ \hline 74 \end{array}

Explanation:

By subtracting the year of adoption (19501950) from the current year (20242024), we find that 7474 years have passed.

Problem 3:

The short version of the National Anthem (consisting of the first and last lines) is sometimes played. It takes about 2020 seconds. How much longer is the full version (5252 seconds) compared to the short version?

Solution:

Difference=52−20=32 seconds\text{Difference} = 52 - 20 = 32 \text{ seconds}

Explanation:

The full version is 3232 seconds longer than the short version played on certain ceremonial occasions.
