Let x be the distance that Anitha is from the fulcrum. For the see-saw to be in a balanced condition I assumed that the point at which the weight was pressing down on the sea-saw times the distance from the fulcrum had to be the same on each side, that is, the numerical values of the products had to be equal to each other. Solved the following for x. 40*10 = 25*x x = 16 cm
