Match the roster form with set builder form. (i) { 1 , 2 , 3 , 6 } (a) { x : x is prime number and a divisor of 6 } (ii) 2 , 3 (b) { x : x is an odd natural number smaller than 10 } (iii) { m , a , t , h , e , i , c , s } (c) { x : x is a natural number an ddivisor of 6 } (iv) { 1 , 3 , 5 , 7 , 9 } (d) { x : x is a letter of the word MATHEMATICS }

Let us consider the set builder forms. (a) { x : x is prime number and a divisor of 6 } ⇒ Prime factorization of 6 = 2 × 3 . where 2 and 3 are prime numbers. ∴ Roster form = { 2 , 3 } . (b) { x : x is an odd natural number smaller than 10 } Odd natural numbers smaller than 10 = 1 , 3 , 5 , 7 , 9 ∴ Roster form = { 1 , 3 , 5 , 7 , 9 } . . (c) { x : x is a natural number and divisor of 6 } ⇒ Factors of 6 are 1 , 2 , 3 and 6 . ∴ Roster form = { 1 , 2 , 3 , 6 } . (d) { x : x is a letter of the word MATHEMATICS } The word MATHEMATICS has the letters: M , A , T , H , E , M , A , T , I , C , S . Here, we see that the letters M , A and T are appearing more than once in the word. We know that while writing a set in roster form, repetition of the elements is not allowed. Writing an element once is sufficient. Therefore, the set in roster form can be written as: Roster form = { M , A , T , H , E , I , C , S } . Therefore, after matching the roster form with the set builder form, the table looks like the following: (i) { 1 , 2 , 3 , 6 } (a) { x : x is a natural number an ddivisor of 6 } (ii) 2 , 3 (b) { x : x is prime number and a divisor of 6 } (iii) { m , a , t , h , e , i , c , s } (c) { x : x is a letter of the word MATHEMATICS } (iv) { 1 , 3 , 5 , 7 , 9 } (d) { x : x is an odd natural number smaller than 10 }
