Assign variables and translate the description into equations literally. Solve the system of equations.

j, Jerry
d, David
f, Frank

Check how the description corresponds to the equations.

Before trying to solve, notice very carefully how d is a formula in terms of j and that f is a formula in terms of j. This will allow a substitution to give you one equation in one unknown variable, j.
