(i) A = {first four natural numbers}

These are equivalent sets as both have equal numbers of elements but not the same.

(ii) A = Set of letters of the word “FOLLOW”

These are equal sets as they have equal and same elements.

(iii) E = {even natural numbers less than 10}

These are equivalent sets as both have equal numbers of elements but not the same.

(iv) A = {days of the week starting with letter S}

B = {days of the week starting with letter T}.

These are equivalent sets as they have equal number of elements

(v) M = {multiples of 2 and 3 between 10 and 20

N = {multiples of 2 and 5 between 10 and 20}.

These are equal sets as they have equal and same elements.

(vi) P = {prime numbers which divide 70 exactly}

Q = {prime numbers which divide 105 exactly}

These are equivalent sets as both have equal numbers of elements.

(vii) A = \left\{0^2,1^2,2^2,3^2,4^2\right\}{0

2 ,1 2 ,2 2 ,3 2

,4

2

} ={0, 1, 4, 9, 16}

B= {16, 9,4, 1, 0}

These are equal sets as they have equal and same elements.

(viii) E = {8,10, 12, 14, 16}

F = {even natural numbers between 6 and 18}

= {8,10,12,14,16}

These are equal sets as they have equal and same elements.

(ix) A = {letters of the word SUPERSTITION}

= {S,U,P,E,R,T,I,O,N}

B = {letters of the word JURISDICTION}.

= {J,U,R,I,S,D,C,T,O,N}

These are neither equal nor equivalent sets as these have different and unequal elements.
