Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

can't we write s'={1/n :n is natural number}
yes , S'= {1/n : n is natural number } union {0}
0 is also limit point .. so take union with {0} also if we vary both (n &m) then limit of S is 0
any doubt ??
if we don't add {0} then will it be wrong?
yes ..
