If x is an integer, then y(y – 1)(y – l) must be evenly divisible by three when l is any of the following values EXCEPT	Choose the correct choice from the following options:
A) -4
B) -3
C) -2
D) 2
E) 5

Solution: We have the product of 3 integers: (y-1)y(y-l).   Note that the product of 3 integers is divisible by 3 if at least one multiple is divisible by 3. Now, to guarantee that at least one integer out of y, (y – 1), and (y – l) is divisible by 3 these numbers must have different remainders upon division by 3, meaning that one of them should have remainder of 1, another reminder of 2 and the last one remainder of 0, so be divisible by 3.   Next, if l=-2 then we'll have (y-1)x(y+2)=(y-1)x(y-1+3) --> which means that (y-1) and (y+2) will have the same remainder upon division by 3. Thus for l=-2 we won't be sure whether (y-1)x(y-l) is divisible by 3.   Answer: -2.

A customer asks the clerk for a paintbrush and a bucket of whitewash for a total price of B dollars. If the paintbrush costs 100 cents less than twice the price of a bucket of whitewash, what is the price of half a bucket of whitewash in dollars?  Choose one.
A) (B + 2)/2.	B) (B + 2)/5.	C) (2B + 200)/3.	D) (B + 2)/3.	E) (B - 2)/6.

Solution: P = 2w - 100   thus total price in cents as given should be   2w-200 +w = 100(B + 2)/5.   3w - 200 = 100 (B + 2)/5.   3w = 100 (B + 2)/5.+200   3w =b+2 (in dollars)   w/2 = (b+2)/6   Ans:(B + 2)/5.

A Jar contains a mixture of AB in the ratio 3:2. When 20 L of Mixture is replaced with liquid B, ratio becomes 2:3. How many liters of liquid A was present in mixture initially.
Choose the correct choice from the following.
A) 12 B) 15 C) 16 D) 20 E) 36

Solution: 20 litres of mixture that is replaced will contain 12 litres of A and 8 litres of B (as A:B = 3:2)   Let the initial volume of the mixture be 3K + 2K = 5K   So by condition ,   [ 3K-12]/ [ 2K-8+20 ]   3  + 2= 
  3  + 2 = 5
5K   So by condition ,   [ 3K-12]/ [ 2K-8+20 ]= 2/3 => 9K-36 = 4K-16+40 => 5K= 60   Solve for K which is K = 12   So initial volume of liquid A = 3K = 36 litres   Answer : 36

Select
A) 83%
B) 80%
C) 20%
D) 17%
E) 12%

Solution: Let's say he works usually 10 hours and earns 100 per hour.   10 * 100= 
10 * 100 = 1_000
1000   10 * 120= 
10 * 120 = 1_200
1200 (this are the new earnings after the raise)   To figure out how much he needs to work with the new salary in order to earn the original 1000:   1000/120= 8.3333   So he can reduce his work by 1.6666 hours. Which is >15%.   Answer 17%.

Solution: Solution: Let the percentage marks in QA =(10a +b)%   Let the percentage marks in DI = (10b +a)%   Let the percentage marks in VA = x%.   Now, according to the question, we have,   [(10a+b) + x + (10b+a)] /3 = x   →11a + 11b + x = 3x.   or, x = 11(a +b) /2.   Clearly, we can see that the percentage of the VA section will be a multiple of 11.   So, required answer will be 66.   Answer: Option 66
