Example 1 Solve 30 x < 200 when (i) x is a natural number 30 x < 200 ๐‘ฅ < 200/30 ๐‘ฅ < 20/3 ๐’™ < 6.66 Since x is a natural number i.e. 1, 2, 3, 4, 5, 6, 7,โ€ฆ. We need to find values of x which is less than or equal to 6 i.e. x can be {1, 2, 3, 4, 5, 6} Example 1 Solve 30 x < 200 when (ii) x is an integer Now, ๐’™ < 6.66 Since x is an integer i.e. โ€ฆโ€ฆ,โˆ’3, โˆ’2, โˆ’1, 0, 1, 2, 3โ€ฆ. We need to find values of x which is less than or equal 6 i.e. x can be โ€ฆโ€ฆ, โˆ’3, โˆ’2, โˆ’1, 0, 1, 2, 3, 4, 5, 6 = {โ€ฆโ€ฆ,โˆ’3, โˆ’2, โˆ’1, 0, 1, 2, 3, 4, 5, 6}
