A club with a total membership of 30 has formed 3 committees, M, S and R, which have 7, 12 and 5 members respectively. If no members of committee M is on either of the other 2 committees, what is the greatest possible number of members in the club who are on none of the committees?	Choose the correct choice from the following choices.
A) 5
B) 7
C) 8
D) 10
E) 11

Solution: As no member of committee M is on either of the other 2 committees then 30-M=30-7= 
30-7 = 23
23 people are on committee S, committee R or on none of the committee. We want to maximize the last group: members in the club who are on none of the committees   General rule for such kind of problems:   to maximize one quantity, minimize the others;   to minimize one quantity, maximize the others.   So we should minimize total # of people who are on committee S and committee R. Now if ALL 5 people who are the members of committee R are also the members of committee S (if R is subset of S) then total # members of committee S and committee R would be minimized and equal to 12. Which means that 23-12= 
23-12 = 11
11 is the greatest possible number of members in the club who are on none of the committees.   Answer: 11.

In a two-digit number, if it is known that its unit's digit exceeds its ten's digit by 2 and that the product of the given number and the sum of its digits is equal to 280, then the number is:  Select the correct option:
A) 16 B) 24 C) 27 D) 35 E) 46

Solution: Let the ten's digit be x. Then, unit's digit = x + 2. Number = 10x + (x + 2) = 11x + 2   Sum of digits = x + (x + 2) = 2x + 2   (11x + 2)(2x + 2) + (  + 2)= 
+ (  + 2) = 2
2x + 2   (11x + 2)(2x + 2)=280   22(x)(x) + 26x - 276 = 0   11(x)(x) + 13x -138 = 0   (x - 3)(11x + 46) = 0   x = 3   Hence, required number = 11x + 2 = 35.   ANSWER:35
