24x<100
⇒x<10024
⇒x<256
(i) It is evident that 1,2,3 and 4 are the only natural numbers less than 256,
Thus when x is a natural number ,the solutions of the given inequality are 1,2,3 and 4.
Hence, in this case, the solution set is {1,2,3,4}.
(ii) The integers less than 256 are .......−3,−2,−1,0,1,2,3,4.
Hence,in this case ,the solution set is {............−3,−2,−1,0,1,2,3,4}.
