Let x be the total number of swans

The number of swans playing on the shore of tank = (7/2)x^(1/2)

The number of swans playing in water = 2

Thus we are required to solve the equation

 x= (7/2)x^(1/2)+2

On solving we find the roots as 1/4 or 16

Since 1/4 is not feasible, the number of swans has to be 16
