The average of 11 numbers is 50. If the average of first 6 numbers is 49 and that of last 6 is 52.Find the 6th number.	Choose the correct choice from the following options:  A) 54  B) 55  C) 56  D) 57  E) 58

Solution: avg = 50 so total sum of 11 numbers = 550   let 6th number is x, so according to the given condition   sum of first 5 numbers = 49*6 - x = 294 - x   sum of last 5 numbers = 52*6 - x = 312 - x   so 6th number x = 550 - (294 - x) - (312 - x) = 2x - 56   so x = 2x - 56 implies x = 56   ANSWER:56

At a dinner party 6 people are to be seated around a circular table. Two sitting arrangements are considered different only when the positions of the people are different relative to each other.What is the total number of possible sitting arrangements or the group?	Pick:
A) 5
B) 10
C) 24
D) 32
E) 120

Solution: Hi there,   You can treat this as an ordering question except thatfor a circular arrangement you need to divide by the number of spaces.So in this case:   6!/6=120   If you spin the circle to right, that doesn't count as a new arrangement. Dividing by the number of spaces takes that into consideration.   Happy Studies,   HG.   120

In May, Xiang sold 15 used cars. For these 15 cars, the range of the selling price was $15,000 and the lowest selling price was $4,500. In June, Xiang sold 10 used cars. For these 10 cars, the range of the selling prices was $16,500 and the lowest selling price was $6,300. What was the range of the selling prices of the 25 used cars sold by Xiang in May and June?	Choose the correct choice from the following answers:	A) 1. $15,600	B) 2. $15,750	C) 3. $16,820	D) 4. $18,300	E) 5. $19,200

Solution: Edited the question as there was a typo.   Range = Highest Value - Lowest Value.   Range in May was 15,000 and the lowest price in May was 4,500, thus the highest price in May was 15,000+4,500=19,500.   Range in June was 16,500 and the lowest price in June was 6,300, thus the highest price in June was 16,500+6,300=22,800.   Lowest price of a car in May-June was 4,500 (May) and the highest price of a car in May-June was 22,800, thus the range for May-June is 22,800-4,500=18,300.   Answer: 4. $18,300.

A certain sum is invested at simple interest at 15% p.a. for two years instead of investing at 12% p.a. for the same time period. Therefore the interest received is more by Rs. 840. Find the sum?
Choose the most appropriate option:
A) Rs. 7000	B) Rs. 9000	C) Rs. 14000	D) Rs. 17000	E) Rs. 27000

Solution: Let the sum be Rs. x.   (x * 15 * 2)/100 - (x * 12 * 2)/100 = 840   => 30x/100 - 24x/100 =840   => 6x/100 = 840   => x = 14000.   ANSWER:Rs. 14000

Choose the most appropriate option.
A) 6 B) 7 C) 8 D) 13 E) 10

Solution: We have:   1) x<y<z 2)="" y-x="">9   3) x</y<z>=2k (x is an even number)   4) y=2n+1 (y is an odd number)   5) z=2p+1 (z is an odd number)   6) z-x=? least value   z-x=2p+1-2k=2p-2k+1=2(p-k)+1 - that means that z-x must be an ODD number. We can eliminate answer choices A, C and E   we are asked to find the least value, so we have to pick the least numbers   since y is odd and x is even, y-x must be odd. since y-x>9, the least value for y-x must be 11, the least value for x must be 2, and, thus, the least possible value for y must be 13 (y-2=11, y=13)   2<13<z, since z is odd, the least possible value for z is 15   z-x=15-2= 
15-2 = 13

Solution: Let the number be a   Given, 10/100 * 30/100 * 50/100 * a = 90   => 1/10 * 3/10 * 1/2 * a = 90   => a = 10 * 20 * 10 * 2 = 6000.   ANSWER:6000
Answer: B
The percentage profit earned by selling an article for $1920 is equal to the percentage loss incurred by selling the same article for $1280. At what price should the article be sold to make 25% profit?
Choose the correct choice from the following
A) $3000  B) $1000  C) $2000  D) $5000  E) $6000

Solution: C   $2000   Let C.P. be $x.   Then, (1920 - x)/x * 100 = (x - 1280)/x * 100   1920 - x = x - 1280   2x = 3200 => x = 1600   Required S.P. = 125 % of $1600 = 125/100 * 1600= 
125/100 * 1600 = 2_000
$2000.

A chemical lab is scheduled to go through two air ventilation systems, a basic system and a more advanced system that takes half an hour and 1.5 hours respectively to fully ventilate the room. If both ventilation systems were to operate at the same time with their respective constant rates, how many hours would it take to fully ventilate the chemical lab?  Choose the correct choice from the following:
A) 1/4	B) 1/3	C) 2/5	D) 5/4	E) 3/8

Solution: The rate of the basic system is 1 room/half hour = 2 rooms per hour   The rate of the advanced system is 1 room/1.5 hours = 2/3 of a room per hour   The combined rate is 8/3 rooms per hour.   The time to ventilate one room is 3/8 of an hour.   The answer is 3/8.

A 5-year investment note offers a 10% return on purchase, and a compounding 5% for each year after the first. If there is a $500 penalty for early redemption, and the note is redeemed for $6430 after the second year, what was the original purchase price? Choose one
A) $ 6,000
B) $ 6,048
C) $ 6,100
D) $ 6,150
E) $ 6,200

Solution: Since the note was redeemed after 2 years, so a penalty of $500 has to be submitted. So the amount that is redeemed after 6430 is after the deduction of $500.   Hence the amount after being compounded is 6930.   Let the initial amount be P.   After the return, the amount becomes 1.1P.   Now use this 1.1P as the principle in the compound interest formula to get the amount 6930.   A=1.1P(1+5/100)A=1.1P(1+5/100)   where A=6930.   Therefore, use   6930=1.1P(1+5/100)6930=1.1P(1+5/100) to get P as $6000.   $ 6,000NSWER:$ 6,000
