There are a total 43800 students in 4 scholl of a city. half the numbe...
Total Students in Four Schools
There are 43,800 students distributed among four schools, denoted as A, B, C, and D.

Equations Based on Given Conditions
We know from the problem statement:
- Half of the number of students in School A: \( \frac{A}{2} \)
- Two-thirds of the number of students in School B: \( \frac{2B}{3} \)
- Three-fourths of the number of students in School C: \( \frac{3C}{4} \)
- Four-fifths of the number of students in School D: \( \frac{4D}{5} \)
All these expressions are equal, so we can set them equal to a common variable \( x \):
- \( \frac{A}{2} = x \) → \( A = 2x \)
- \( \frac{2B}{3} = x \) → \( B = \frac{3x}{2} \)
- \( \frac{3C}{4} = x \) → \( C = \frac{4x}{3} \)
- \( \frac{4D}{5} = x \) → \( D = \frac{5x}{4} \)

Total Students Equation
Now summing all schools gives:
\[
A + B + C + D = 2x + \frac{3x}{2} + \frac{4x}{3} + \frac{5x}{4} = 43800
\]
To combine these, find a common denominator, which is 12:
- \( A = \frac{24x}{12} \)
- \( B = \frac{18x}{12} \)
- \( C = \frac{16x}{12} \)
- \( D = \frac{15x}{12} \)
Thus, summing yields:
\[
\frac{24x + 18x + 16x + 15x}{12} = 43800
\]
This simplifies to:
\[
\frac{73x}{12} = 43800
\]
Solving for \( x \):
\[
73x = 43800 \times 12 \quad \Rightarrow \quad x = \frac{525600}{73} \approx 7200
\]

Calculating Students in Each School
Now substituting \( x \) back to find each school’s students:
- \( A = 2x = 14400 \)
- \( B = \frac{3x}{2} = 10800 \)
- \( C = \frac{4x}{3} = 9600 \)
- \( D = \frac{5x}{4} = 9000 \)

Final Ratio of Students in School A to D
The ratio of students in School A to School D is:
\[
\text{Ratio} = \frac{A}{D} = \frac{14400}{9000} = \frac{16}{10} = \frac{8}{5}
\]
Thus, the final ratio of students in School A to School D is **8:5**.

Similar UPSC Doubts

Aniket was from a very rich family, with its heritage in the village of Adpur in Gujarat. He was sent to a school in the city for the best education, where he stayed on until after post-graduation. With the fast paced life of upper-class pursuits Aniket rarely saw the ground below. One day on a visit to his village, he came across a lanky little girl. All of nine years, maybe even seven it is difficult to tell in poorly-fed children. Falsely made up, oiled hair, nose rings and an outsized purple ribbon that stared out from behind her head shecut a pathetic picture. She had just been sold for Rs 5,000 to a city- bred man, who was taking her with him to look after his newborn. The life he had known never indicated that there were many who lived a different life. Purple ribbons buyer griped that Rs 5,000 was too much, refusing to buy. The broker pleaded, Where will she go, poor thing? Keep her as your servant, she will make your tea... and offered to cut the price to Rs 4,500. Anikets stomach churned. Was this the value of a child? As he drove to the city, he felt chased by the nine-year-olds scrubbed face framed by outsized purple ribbons. Unable to live with this memory, and seeking a solution, which he knew his gaggle of friends would not be able to provide, Aniket went back to Adpur determined to change what he had seen.Q. Aniket went to the best schools in India and asked them if they would help. I will support you financially, you just come to my village and open a school. But they all declined. Adpur was notorious for crime and was extremely unsafe, they pointed out. How should Aniket react?

Passage - 5Access to schooling for those coming of school age is close to universal, but access to quality exhibits a sharp gradient with socio-economic status. Quotas for the weaker sections in private schools is a provision introduced by the Right of Children to Free and Compulsory Education Act, 2009. The quotas have imposed a debate on issues of social integration and equity in education that private actors had escaped by and large, The idea of egalitarian education system with equality of opportunity as its primary goal appears to be outside the space that private school principals inhabit. Therefore, the imposition of the quotas has led to resistance, sometimes justified,Q. With reference to the above passage, the following assumptions have been made:1. Making equality of opportunity a reality is the fundamental goal of the Indian education system.2. The present Indian school system is unable to provide egalitarian education.3. Abolition of private schools and establishment of more government schools is the only way to ensure egalitarian education.Q.Which of the above assumptions is/are valid?
