In the above number, A and B represent the tens and units digits, respectively. If the above number is divisible by 35, what is the greatest possible value of B x A?  Choose the most appropriate option.
A) 0	B) 10	C) 20	D) 30	E) 35
I also was confused when I was looking forabove number:D   As far as I understood, 35 is a factor of AB. In other words, the values of B (units digits can be 5 or 0. Better to have option for 5 in this case to havebigger result). Now let's try 35x1 (A=3, B=5 respectively we have =15). But we don't have this number in answer choices, move on. (avoid even multiples of 2,4,6,8 etc (we will have 0 in units thus making our result 0)   35x3 = 105 (A=0 B=5 respectively. Hey! that's 0 now.   35x5= 175 (A=7, B=5 respectively. Increasing trend , we have 35 now). This is the greatest possible value of B x A.   IMO 35.
