Lean Mix - contains low quantity of cement
Rich mix - contains high quantity of cement.

As the description says leqn mix have low strength compare to rich mixes.
Lean mixes are generally use for bedding mortar of flooring, filling gaps between 2 materials like brickwork and rcc beam etc.

Rich mixes are used for doing works which also requires some strength properties and generally used in brickwork, plaster etc.

Very rich mix - they contains very high amount of cement and generally use in sealing gaps repairs etc.
