15x less than 73, where (i)x belongs to N and (ii) Z.

solve the inequation and represent the solution set on the number line.

15x<73Now considering first case when, xN , 15x<73or  x<7315 or x<4.8 But x is natural number so x=1,2,3,4 are the required value of x. 


on the number line these values are shown as A,B,C and D.

Case-2-
when xZ then, x<4.8 can be shown as, x(-, 4.8) and on number line it can be shown as,
