They have solved 2 sets of simultaneous equations and taken the average of the 4 equations:

 

y * x^25 =2100.....................(1)

y* x^35 =2800......................(2)

 

y* x^55 =5050.....................(3)

y* x^125 =40325.................(4)

 

When you solve these equations and take their average, you get x =~3% and y =~997.
