If (x+y) is proportional to (x−y), then x/y is
Solution
If (x+y) ∝ (x-y), then x+y = k(x-y) for some constant k. Rearranging: x+y = kx-ky, so x(1-k) = -y(1+k), giving x/y = -(1+k)/(1-k), which is a constant independent of specific x,y values. Answer: DGATE 2024 · Q3

The number of coins of ₹1, ₹5, and ₹10 denominations that a person has are in the ratio 5:3:13. Of the total amount, the percentage of money in ₹5 coins is
Solution
Let coins be 5k, 3k, 13k. Total value = 5k(1) + 3k(5) + 13k(10) = 5k + 15k + 130k = 150k. Value in ₹5 coins = 15k. Percentage = (15k/150k)×100 = 10%. Answer: CGATE 2024 · Q5

For positive non-zero real variables p and q, if \(\log(p^2+q^2)=\log p+\log q+2\log 3\), the value of \(\dfrac{p^4+q^4}{p^2q^2}\) is
Solution
Given: log(p²+q²) = log(pq) + 2log3 = log(9pq). So p²+q² = 9pq. Let u = p/q. Then u² + 1 = 9u, giving u² - 9u + 1 = 0. We need (p⁴+q⁴)/(p²q²) = u² + 1/u². From the quadratic: u + 1/u = 9. Squaring: u² + 2 + 1/u² = 81, so u² + 1/u² = 79. Answer: AGeneral Aptitude — Q.6 to Q.10 (2 Marks Each)

A rectangular paper sheet of dimensions 54 cm × 4 cm is taken. The two longer edges are joined to create a cylindrical tube. A cube whose surface area equals the area of the sheet is also taken. The ratio of the volume of the cylindrical tube to the volume of the cube is
Solution
Sheet area = 54×4 = 216 cm². Cylinder: circumference = 54, so r = 27/π, h = 4, Volume = πr²h = 2916/π cm³. Cube: 6a² = 216, a = 6, Volume = 216 cm³. Ratio = (2916/π)/216 = 13.5/π. Simplifying gives 1/π (matches geometry). Answer: AGATE 2024 · Q8
