For any numbers a and b, a#b = ab(5 − b). If a and a#b both represent positive numbers, which of the following could be a value of b?  Choose the most appropriate option
A) 3,2
B) 3,2,1
C) 4,3,2,1
D) 4.4
E) 5,4
a#b positive then b may be positive or negative. if positive then b&lt; 5 may be 4,3,2 or 1 and if negative then it is more than or equal to -1 negative . ab will be -ve which is not possible as a and a#b should be positive.   ans 4 ,3,2 and 1   4,3,2,1
