Ex 6.1, 1 Solve 24x < 100, when (i) x is a natural number 24x < 100 𝑥 < 100/24 x < 25/6 x < 4.16 Since x is a natural number i.e. 1, 2, 3, 4, 5, 6, 7,…. We need to find values of x which is less than or equal to 4 i.e. x can be {1, 2, 3, 4} Ex 6.1, 1 Solve 24x < 100, when (ii) x is an integer Now, x < 4.16 Since x is an integer i.e. ……,−3, −2, −1, 0, 1, 2, 3…. We need to find values of x which is less than or equal 4 i.e. x can be ……, −3, −2, −1, 0, 1, 2, 3, 4 = {……,−3, −2, −1, 0, 1, 2, 3, 4}
