Find x, the days Mr. Tung has worked.

Mr. Tung's daily wage is (3600/x).

Mr. Pang's daily wage is (3600/x)-100.

Mr. Pang worked (x+3) days.

Therefore:

3600 = (3600/x -100)(x+3)

Multiply by x/100:

36x = (36-x)(3+x)

Expand and rearrange into quadratic form. Then find the quadratic roots. At least one root will be the number of days Mr. Tung has worked.
