T = a set of first 4 prime numbers R= a set of numbers up to 50 exactly divisi
P= a set of Provinces in Nepal
N= {x:x is a natural number less than 8.}
M= {x :x is a multiple of 5; 10 SX 25.}
L = {x:x is a letter in the word 'mathemati
write the following sets by (i) describing members

The answer to the question is given in the explanation section.

Explanation:

Prime numbers are those number which is not divisible by other number except itself.

T={2,3,5,7}

In R set I have to write numbers which are divisible by other number means number not prime.

R={4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,30,32,33,34,35,36,38,39,40,42,44,45,46,48,49}

In Set P i have to list down the names of the provinces of Nepal. Currently there are 7 Provinces.  

In Set N I have to write Natural No less that 8

N={1,2,3,4,5,6,7}

In set  M I have to write multiple of 5, 10,20. 25

Multiple of 5 are: 1 and 5

Multiple of 10 are: 1,2,5,10

Multiple of 20 are: 1,2,5,4,10

Multiple o 25 are: 1,5,25

For the set L I have to write letter of the word 'mathemati'

As repetition is not significant in set so i have skep the repetition

L={m,a,t,h,e,i}

answer; i believe that the correct answer is (a)
