1.	The number of constant functions possiblfrom R to B where B- 2,4,6,8,..24) are1) 24 2) 125053) 84) 6
Answer» Number of Constant functions possible in this case = Number of elements in set B Elements in set B forms an AP with First term, a = 2; Common Difference, d = 2 Let n be the number of elements in set B. Thus, 24 = a +(n-1)d = 2 + (n-1)d 22 = (n-1)*2 (n-1) = 11n = 12 Therefore, there are 12 elements in B and thus the total constant functions are 12. Hence, Option 2 is correct

Answer»

Number of Constant functions possible in this case = Number of elements in set B

Elements in set B forms an AP with First term, a = 2; Common Difference, d = 2

Let n be the number of elements in set B.

Thus, 24 = a +(n-1)d = 2 + (n-1)d 22 = (n-1)*2 (n-1) = 11n = 12

Therefore, there are 12 elements in B and thus the total constant functions are 12.

Hence, Option 2 is correct
