Start: Sita = 50x, Gira = 60x, Mita = 70x
After 1st hike: S = 60x, G = 75x, M = 84x
After 2nd hike: S = 84x, G = y (unknown), M = 105x
Now, y = (84x + y + 105x)/3
or, 2y = 189x
or, y = 94.5x
Means, Gita's salary increased from 75x to 94.5x; an increase of 19.5x
Therefore, % change = (1950/75) = 26%
