Answer:

Solution :-

(i) A = {x: x is an odd natural number}

A = {1 , 3 , 5, 7, 9....}

(ii) B = {x: x is an integer, -1/2 < x < 9/2}

B = {0, 1, 2, 3, 4}

(iii) C = {x: x is an integer, x² ≤ 4}

C = {-2, -1, 0, 1, 2}

(iv) D = {x: x is a letter in the word “LÒYAL”}

There are 4 letters in LÒYAL. L,O,Y,A [Because L is repeated 2 times}

D = {L, O, Y, A}

(v) E = {x: x is a month of a year not having 31 days}

Months that have not 31 days are - February, April, June, September, November

E = {February, April, June, September, November}

(vi) F = {x: x is a consonant in the English alphabet which proceeds k}.

{b, c, d, f, g, h, j}
