If x and y are different prime numbers, each greater than 6, which of the following must be true? I. x+y is an even integer II. xy is an odd integer III. (x/y) is not an integer  Pick:
A) II only	B) II,III only	C) I,II and III	D) III only	E) I only

Solution: Given: x and y are different prime numbers, both greater than 6   Statement I: x+y is an even integer   Since x and y are prime numbers greater than 6, they will be odd   Therefore sum will be even.   Correct   Statement II: xy is an odd integer   Since x and y are prime numbers greater than 6, they will be odd   Therefore multiplication will be odd.   I,II and IIIorrect   Statement III: (x/y) is not an integer   Since x and y are prime integers, therefore they will not have any common factor apart from 1   Hence (x/y) will not be an integer   I,II and IIIorrect   Hence all three statements I, II and III are correct   Answer : I,II and III

Two varieties of wheat - A and B costing Rs. 9 per kg and Rs. 15 per kg were mixed in the ratio 3:7. If 5 kg of the mixture is sold at 25% profit, find the profit made?	Choices:
A) Rs. 15.50
B) Rs. 16.90
C) Rs. 13.50
D) Rs. 16.50
E) Rs. 16.40

Solution: Let the quantities of A and B mixed be 3x kg and 7x kg.   Cost of 3x kg of A = 9(3x) = Rs. 27x   Cost of 7x kg of B = 15(7x) = Rs. 105x   Cost of 10x kg of the mixture = 27x + 105x = Rs. 132x   Cost of 5 kg of the mixture = 132x/10x (5) = Rs. 66   Profit made in selling 5 kg of the mixture = 25/100 (cost of 5 kg of the mixture) = 25/100 * 66 = Rs. 16.50   Answer:Rs. 16.50

A) d  B) 6d  C) 6d+6  D) 6d+12  E) 6d+18

Solution: CONCEPT: Standard Deviation is Defined as Average Deviation of Terms in the set from the Mean value of the set. i.e.   1) It depends on the separation between the successive terms of the set   2) If a Constant Value is Added/Subtracted in every terms of set then the Separation between successive terms does NOT change Hence S.D. remains Constant   e.g.{1, 2, 3, 4, 5} will have same standard Deviation as {1+10, 2+10, 3+10, 4+10, 5+10}   3) If a Constant Value is Multiplied in every terms then the Separation between succesive terms gets multiplied by the constant Hence S.D. remains gets multiplied by same Number   e.g. {0.7, 1.4, 2.1, 2.8, 3.5} will have Standard Deviation = 0.7* Standard deviation of set {1, 2, 3, 4, 5}   When 6 is added in each term of set {a, b,c} then the new set {a+6, b+6, c+6} will remain same as the previous standard deviation i.e. d   dnswer: d

A survey of n people in the town of Eros found that 50% of them preferred Brand A. Another survey of 120 people in the town of Angie found that 60% preferred Brand A. In total, 55% of all the people surveyed together preferred Brand A. What is the total number of people surveyed?  Choices:
A) 50
B) 100
C) 150
D) 200
E) 240

A = {2, 3, 4, 5}
B = {4, 5, 6, 7, 8}
Two integers will be randomly selected from the sets above, one integer from set A and one integer from set B. What is the probability Q that the sum of the two integers will equal 9 ?  Select the correct option: A) 0.15 B) 0.20 C) 0.25 D) 0.30 E) 0.33

Solution: Rearrange the first set:   A = {5,4,3,2}   B = {4,5,6,7, 8}   As you can see numbers in each column (the numbers of the same color) give the sum of 9. So there are 4 such pares possible, total # of pairs is 4*5= 
4*5 = 20
20. Q=favorable/total=4/20=0.2.   Answer: B.   Or: we can select ANY number from set A (4/4=1) but in this case we must select its matching pair from set B (the number of the same color) and since there are only one matching pair of this particular number in B then the probability of this is 1/5. So, overall: Q=1*1/5.   Answer: 0.20.
Answer: B

Choose the correct choice from the following choices
A) 12  B) 15  C) 13  D) 14  E) None of these

Solution: Explanation:   16 men and 12 children can do work in 26 days =>in one day   16 *26= 
16 *26 = 416

12*26 = 312
312 children can do same work   also, 13 men can do same work in 48 days=>13 *48= 
13 *48 = 624
624 men   thus 624 men= 412 men + 312 children   => 2mne = 3 children   24 men can do a work in 26 days   16 men can do same work in =26*24/16= 
26*24/16 = 39
39 days   Answer: Option 14
