Abstract We discuss Whether the numbers of x-ray and radio-produced electrons in solar flares are the same. The number of the radio-produced electrons that is estimated with an inhomogeneous source increases by a factor of 103-104 because of the inhomogeneity and the decreased magnetic field (B=120 G) of the radio source. The number of the x-ray-produced electrons decreases by a factor of 10 - 30 due to the increase of the number density of ions (3 x 1010cm-3). These are the reasons why the number of radio-produced electrons is approximately equal to that of x-ray produced in the 1981 April 27 burst.
