A laboratory adopts slightly modified fundamental units. The unit of mass is reduced by 2%, the unit of length is increased by 3%, and the unit of time is decreased by 1% compared with the SI units.
(i) Write the dimensional formula of density.
(ii) Calculate the approximate percentage change that will occur in the numerical value of density when expressed in this new set of units.
