$$\lceil\frac{{x}}{{a}}\rceil={n}<{a} \\ $$ $$\lceil\frac{{x}}{{a}}\rceil={n}<\lceil{a}\rceil−\mathrm{1} \\ $$ $$\frac{{x}}{{a}}\leqslant{n} \\ $$ $${x}\leqslant{na}<\left(\lceil{a}\rceil−\mathrm{1}\right){a} \\ $$ $$\Rightarrow{solution}\:{is}\:{x}<\left(\lceil{a}\rceil−\mathrm{1}\right){a} \\ $$ | ||
