CSIR NET MATHEMATICS JUNE 2012 QUESTION & ANSWER
Part B
- The number of words that can be formed permuting the letters of the word 'MATHEMATICS' is ...........
Answer:
number of letters in the word 'MATHEMATICS' = 11.In the word 'MATHEMATICS' M occurs 2 times, A 2 times, T 2 times, other letters 1 time. Required number of permutations = 11!/ 2! 2! 2! = 4989600. - Number of divisors of 50,000 = ............
Answer: Factorise 50,000 as 5 x 10,000 = 5 x 10^4 = 5 x 2^4 x 5^4 = 2^4 x 5 ^ 5.
Number of divisors of 50,000 = ( 4+1) (5+1) = 30. - The radius of convergence of the series
