Abhishek starts to paint a fence on one day. On the second day, two more friends of Abhishek join him. On the third day 3 more friends of him join him and so on. If the fence is completely painted this way in exactly 20 days, then find the number of days in which 10 girls painting together can paint the fence completely, given that every girl can paint twice as fast as Abhishek and his friends(Boys)? (Assume that the friends of Abhishek are all boys).
Answers
A) 20	B) 40	C) 45	D) 77	E) 87

Solution: Number of men working on first day = 1   Number of men working on second day = 3   Number of men working on second day = 6 and so on..   Total number of boys till the end of the work = [n(n + 1) (n + 2)] / 6   = [20 x 21 x 22] / 6 = 1540   Given that every girl paints twice as fast as Abhishek’s friends.   Hence, 20 girls work is being done.   Thus, the number of days taken to paint the fence = 1540/20= 
1540/20 = 77

Henry eats X scones in X percent of the time it takes Rachel to eat Y scones. If Rachel eats four scones in ten minutes, then the number of minutes it takes Henry to eat 10 scones must be equal to which of the following? Choose the most appropriate option:
A) Y/4  B) 200/Y  C) 100Y/(6X)  D) XY/200  E) Y/(5X)

Solution: Rachel eats 4 scones/10 minutes = 2/5 scones per minute   The time for Rachel to eat 1 scone is 5/2 minutes.   The time for Rachel to eat Y scones is 5Y/2 minutes.   The time for Henry to eat X scones is 5YX/200 minutes.   The time for Henry to eat 1 scone is 5Y/200 minutes.   The time for Henry to eat 10 scones is 50Y/200 = Y/4 minutes.   The answer is Y/4.

A person takes 5hrs 45 min in walking to a place and ridingback. He would have gained 2hrs by riding both ways. The time he would take to walk both ways is?
Choose the correct choice from the following options:
A) 6 hours 23 min  B) 6 hours 40 min  C) 7 hours  D) 7 hours 45 min  E) 8 hours

Solution: ----------------------------------------------------------------   Solution 1   ----------------------------------------------------------------   Given that time taken for riding both ways will be 2 hours lesser than   the time needed for waking one way and riding back   From this, we can understand that   time needed for riding one way = time needed for waking one way - 2 hours   Given that time taken in walking one way and riding back = 5 hours 45 min   Hence The time he would take to walk both ways = 5 hours 45 min + 2 hours = 7 hours 45 min   In fact, you can do all these calculations mentally and save a lot of time   which will be a real benefit for you.   7 hours 45 min

How many different three letter words can be formed (the words need not be meaningful) using the letters of the word MEDITERRANEAN such that the first letter is E and the last letter is R?	Choose the correct choice from the following answers:
A) 59
B) 11!/(2!*2!*2!)
C) 56
D) 54
E) 11!/(3!*2!*2!*2!)

Solution: E- -R   We are left with the following 11 letters: {M, D, I, T, R, EE, AA, NN} out of which 8 are distinct: {M, D, I, T, R, E, A, N}.   We should consider two cases:   1. If the two middle letters are the same, we'd have 3 words: EEER, EAAR and ENNR.   2. If the two middle letters are distinct, then we are basically choosing 2 letters out of 8 when the order of the selection matters, so it's 8P2 = 56.   Total = 56 + 3 = 54.   Answer:54

A) 17 km/hr
B) 89 km/hr
C) 36 km/hr
D) 89 km/hr
E) 82 km/hr

Solution: Let the speed of each train be x m/sec.   Then, relative speed of the two trains = 2x m/sec.   So, 2x = (120 + 120)/12 => x = 10   Speed of each train = 10 m/sec.   = 10 * 18/5 =- 36 km/hr.   Answer: 36 km/hr

Ben is driving on the highway at z miles per hour. (One mile equals 5,280 feet.) Ben's tires have a circumference of y feet. Which of the following expressions gives the number of revolutions each wheel turns in one hour?
Options:
A) 5,280(z/y)
B) 5,280(y/x)
C) 5,280(xy)
D) 5,280/(xy)
E) (xy)/5,280

Solution: In one hour, at the rate of z miles per hour, Ben covers z miles, so 5,280z feet.   The number of revolutions = distance/circumference = 5,280z/y.   5,280(z/y)nswer: 5,280(z/y).
Answer: A
The grade point average of one third of the classroom is 15; the grade point average of the rest is 18. What is the grade point average of the whole class?  Choose the correct choice.
A) 17 B) 19 C) 21 D) 23 E) 25

Solution: Let n=total students in class   total points for 1/3 class=15n/3=5n   total points for 2/3 class15 /3= 
15 /3 = 5
5n   total points for 2/3 class=18*2n/3=12n   total points for whole class18*2 /3= 
18*2 /3 = 12
12n   total points for whole class=5n+12n=17n   17n total class points/n total students5 +12= 
5 +12 = 17
17n   17n total class points/n total students=17 grade point average for total class   17nswer : 17
Answer: A
The percentage profit earned by selling an article for Rs. 1920 is equal to the percentage loss incurred by selling the same article for Rs. 1280. At what price should the article be sold to make 15% profit? Answers:
A) 2000
B) 2778
C) 1840
D) 2778
E) 2771

Solution: Let C.P. be Rs. x.   Then, (1920 - x)/x * 100 = (x - 1280)/x * 100   1920 - x = x - 1280   2x = 3200 => x = 1600   Required S.P. = 115 % of Rs. 1600 = 115/100 * 1600 = Rs. 1840.   Answer:1840
Answer: C
Company C produces toy trucks at a cost of $5.00 each for the first 100 trucks and $3.50 for each additional truck. If 500 toy trucks were produced by Company C and sold for $12.00 each, what was Company C’s gross profit?	Choose the correct option.
A) $2,250	B) $2,500	C) $4,100	D) $3,250	E) $4,500

Solution: $4,100ost of 500 trucks: (100 * 5 ) + (400 * 3.5) = 500 + 1400= 
500 + 1400 = 1_900
$ 1900   Revenue :  500 * 12= 
 500 * 12 = 6_000
$6000   Profit:   6000 - 1900= 
  6000 - 1900 = 4_100
$ 4100   Option $4,100 is correct

Answer: E
The total of company C's assets in 1994 was 300% greater than the total in 1993, which in turn was 500% greater than the total in 1992. If the total of company C's assets in in 1992 was N dollars, which one of the following represents company C's assets in 1994: Choose the correct choice:
A) 7N
B) 8N
C) 9N
D) 24
E) 20

Solution: Let's use actual numbers. Starting in 1992, let's say company C had $100 in assets.   In 1993, the total assets were 500% GREATER, which means 1992 PLUS 500% of 1992:   $100 + 5x$100 = $100 + $500 =$600   In 1994, the total assets were 300% GREATER than they were in 1993, which means 1993 PLUS 300% of 1993:   $600 + 3x$600 100 +  500= 
100 +  500 = 600
$600   In 1994, the total assets were 300% GREATER than they were in 1993, which means 1993 PLUS 300% of 1993:   $600 + 3x$600= $600 + $1800 =$2400   This is 24 times the 1992 number, so the correct answer is 24N.   24600 +  1800= 
600 +  1800 = 2_400
$2400   This is 24 times the 1992 number, so the correct answer is 24N.   24
Answer: D
A sum of money amounts to Rs. 9800 after 5 years and Rs. 12005 after 8 years at the same rate of simple interest. The rate of interest per annum is:	Options
A) 5%
B) 8%
C) 12%
D) 15%
E) 18%

Solution: S.I. for 3 years = Rs. (12005 - 9800) = Rs. 2205.   S.I. for 5 years = Rs.(2205x5)/3= Rs. 3675   Principal = Rs. (9800 - 3675) = Rs. 6125.   Hence, rate = (100 x 3675)/(6125x5)	%	= 12% ANSWER :12%
Answer: C
