The number obtained by interchanging the digits of a two-digit number is less than the original number by 36. The sum of the digits of the number is 8. What is the original number ? Choose the correct choice:
A) 71
B) 62
C) 53
D) 35
E) 45

Solution: Explanation :   Let the number be 10x + y.   ∴ x + y = 8 .....(i)   10x + y - (10y + x) = 36 ∴ 9(x - y) = 3   ∴ x - y = 4 .......(ii)   From equation (i) and (ii): x = 6, y = 2   ∴ Number = 62   Answer : Option 62

The dimensions of a room are 25 feet * 15 feet * 12 feet. What is the cost of white washing the four walls of the room at Rs. 9 per square feet if there is one door of dimensions 6 feet * 3 feet and three WINDOWS of dimensions 4 feet * 3 feet each?  Choose one
A) 4000  B) 345  C) 5673  D) 6530  E) 8154

Solution: Area of the four walls = 2h(l + b)   Since there are doors and WINDOWS, area of the walls = 2 * 12 (15 + 25) - (6 * 3) - 3(4 * 3) = 906 sq.ft.   Total cost = 906 * 9 = Rs.8154   Answer: Option 8154

There is a right angle triangle inside a circle of diameter 18cm. Inside this triangle ,there is another circle of diameter 6 cm. Find the perimeter of the triangle.
Select the correct option:  A) 24cm  B) 36*2^1/2cm  C) 36cm  D) 54cm  E) 42cm

Solution: 1)The radius of the incircle of a right triangle with legs a and b and hypotenuse c is r=(a+b-c)/2   2)The radius of the circumcircle is half the length of the hypotenuse R=c/2   3)Thus the sum of the circumradius and the inradius is half the sum of the legs R+r=(a+b)/2   From 2nd Rule c=18cm   From 3rd Rule a+b= 2*(9+3)= 
2*(9+3) = 24
24cm   Hence Perimeter a+b+c= 24+18= 
24+18 = 42

Which is better investment, 12% stock at par with an income tax at the rate of 5paise per rupee or 14 2/7 % stock at 120 free from income tax? Choose the correct option
A) 12%  B) 14 2/7%  C) Both are equally good  D) Cannot be compared  E) None of these

Solution: Let the investment in each (100*120)   Income in first case = (12/100*100*120)= 
(12/100*100*120) = 1_440
1440   Net income=(1440-5/100*1440)= 
(1440-5/100*1440) = 1_368
1368   Income in second case=((100/2*20)*100*120)=1428.57   Clearly, 14 2/7 % stock at 120 is better   Option 14 2/7%

In how many ways can 5 different toys be packed in 3 identical boxes such that no box is empty, if any of the boxes may hold all of the toys ? Choose the correct choice from the following answers
A) 22	B) 25	C) 88	D) 17	E) 10

Solution: The toys are different; The boxes are identical   If none of the boxes is to remain empty, then we can pack the toys in one of the following ways   a. 2, 2, 1   b. 3, 1, 1   Case a. Number of ways of achieving the first option 2 - 2 - 1   Two toys out of the 5 can be selected in \inline {\color{Black} 5C_{2}} ways. Another 2 out of the remaining 3 can be selected in \inline {\color{Black} 3C_{2}} ways and the last toy can be selected in \inline {\color{Black} 1C_{1}} way.   However, as the boxes are identical, the two different ways of selecting which box holds the first two toys and which one holds the second set of two toys will look the same. Hence, we need to divide the result by 2   Therefore, total number of ways of achieving the 2 - 2 - 1 option is ways \inline {\color{Black} 5C_{2}\times 3C_{2}}= 15 ways   Case b. Number of ways of achieving the second option 3 - 1 - 1   Three toys out of the 5 can be selected in \inline {\color{Black} 5C_{3}} ways. As the boxes are identical, the remaining two toys can go into the two identical looking boxes in only one way.   Therefore, total number of ways of getting the 3 - 1 - 1 option is \inline {\color{Black} 5C_{3}} = 10 = 10 ways.   Total ways in which the 5 toys can be packed in 3 identical boxes   = number of ways of achieving Case a + number of ways of achieving Case b   = 15 + 10= 
15 + 10 = 25
25 ways.   Answer: 25

Two persons start running simultaneously around a circular track of length 300 m from the same point at speeds of 15 km/hr and 25 km/hr. When will they meet for the first time any where on the track if they are moving in opposite directions?  Choose one.
A) 76 seconds B) 16 seconds C) 18 seconds D) 27 seconds E) 19 seconds

Solution: Time taken to meet for the first time anywhere on the track   = length of the track / relative speed   = 300 / (15 + 25)5/18 = 300* 18 / 40 * 5 = 27 seconds.   Answer: 27 seconds

What number is obtained by adding the units digits of 734^98 and 347^82? Choices:  A) 11  B) 12  C) 13  D) 14  E) 15

Solution: The units digit of 734^98 is 6 because 4 raised to the power of an even integer ends in 6.   The units digit of 347^82 is 9 because powers of 7 end in 7, 9, 3, or 1 cyclically. Since 82 is in the form 4n+2, the units digit is 9.   Then   6+9= 
  6+9 = 15

A prize of $1200 is to be distributed among 40 winners, each of whom must be awarded at least $40. If 2/5 of the prize will be distributed to 3/5 of the winners, what is the greatest possible individual award?	Choose the correct choice from the following choices:
A) $100 B) $120 C) $280 D) $300 E) $360

Solution: Total value of the prize =$1200   Number of people = 40   2/5 of 1200 (=$480) should be distributed among 3/5 of 40 (=24 people ) with each getting $40 each. Remaining money = 1200-480= 
1200-480 = 720
$720. Now in order to 'maximize' 1 prize, we need to minimise the others and we have been given that each should get $40. Thus, minimising the remaining 15 people (=40-24-1. '-1' to exclude 1 that needs to be maximised) = 15*40= 
15*40 = 600
600.   Thus the maximum award can be= 720-600= 
720-600 = 120
$120, hence $120 is the correct answer.

Rs.1200 divided among P, Q and R. P gets half of the total amount received by Q and R. Q gets one-third of the total amount received by P and R. Find the amount received by R? Choose the correct option.
A) Rs.400	B) Rs.500	C) Rs.300	D) Rs.600	E) None of these

Solution: Let the amounts to be received by P, Q and R be p, q and r.   p + q + r = 1200   p = 1/2 (q + r) => 2p = q + r   Adding 'p' both sides, 3p = p + q + r = 1200   => p = Rs.400   q = 1/3 (p + r) => 3q = p + r   Adding 'q' both sides, 4q = p + q + r = 1200   => q = Rs.300   r = 1200 - (p + q) => r = Rs.500.   ANSWER:Rs.500

Two trains 150 meters and 180 meters long are running in the same direction with speeds of 102 km/hr, 66km/hr. In how much time will the first train cross the second  Options:
A) 37 sec
B) 22 sec
C) 27 sec
D) 35 sec
E) 33 sec

Solution: Explanation:   Relative speed of the trains = (102 - 66) km/hr = 36 km/hr   = (36Ã— 5/18) m/sec = 10 m/sec.   Time taken by the trains to cross each other   = Time taken to cover (150 + 180) m at 10 m /sec = (330/10)=

An alloy of copper and zinc contains copper and zinc in the ratio 8 : 2. Another alloy of copper and zinc contains copper and zinc in the ratio 4 : 6. In what ratio should the two alloys be mixed so that the resultant alloy contains equal proportions of copper and zinc? Pick one:	A) 5 : 1	B) 4 : 1	C) 3 : 1	D) 6 : 1	E) 8 : 1

Solution: Let Alloy_1 be x units, and let Alloy_2 be y units.   So, fraction of copper in Alloy_1 = 8x/10, and fraction of zinc in Alloy_1 = 2x/10   Similarly, fraction of copper in Alloy_2 = 4y/10, and fraction of zinc in Alloy_2 = 6y/10.   Mixing them, we get   copper = 8x/10 +4y/10; zinc = 2x/10 + 6y/10   So, 8x+4y = 2x+6y   -> 6x = 2y   -> x/y =6/2= 
6/2 = 3
3/1   So, they must be mixed in the ratio 3 : 1   Answer : 3 : 1

Mr. Kramer, the losing candidate in a two-candidate election, received 942,568 votes, which was exactly 30 percent of all votes cast. Approximately what percent of the remaining votes would he need to have received in order to have won at least 50 percent of all the votes cast?  Choose one:
