WAEC (WASSCE) Mathematics questions on Variation
- WAEC 2024A variable W varies partly as M and Partly inversely as P. Which of the following correctly represents the relation with k 1 and k 2 constants?
- WAEC 2023M varies jointly as the square of n and square root of q. If M = 24 when n = 2 and q = 4, find M when n = 5, q = 9.
- WAEC 2022M varies directly as n and inversely as the square of p. If M= 3 when n = 2 and p = 1, find M in terms of n and p.
- WAEC 2020Given that x is directly proportional to y and inversely proportional to Z, x = 15 when y = 10 and Z = 4, find the equation connecting x, y and z
- WAEC 2019H varies directly as p and inversely as the square of y. If H = 1, p = 8 and y = 2, find H in terms of p and y.
