For any numbers a and b, a#b = ab(7 − b). If a and a#b both represent positive numbers, which of the following could be a value of b?
Choose the correct choice from the following options.
A) 6,5,	B) 6,5,4,	C) 6,5,4,3,	D) 6,5,4,3,2	E) 6,5,4,3,2,1
a#b positive then b may be positive or negative. if positive then b&lt; 7 may be 6,5,4,3,2 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 6,5,4,3,2,1   6,5,4,3,2,1
