A man misses a bus by 40 minutes if he travels at 30 kmph. If he travels at 40 kmph, then also he misses the bus by 10 minutes. What is the minimum speed required to catch the bus on time?
Choose the correct choice from the following choices:  A) 22  B) 45  C) 66  D) 88  E) 12

Solution: Let the distance to be travelled to catch the bus be x km   x/30 - x/40 = 30/60 => (4x - 3x)/120 = 1/2 => x = 60 km   By traavelling 30 kmph time taken = 60/30= 
60/30 = 2
2 hours   By taking 2 hours, he is late by 40 min. So, he has to cover 60 km in at most speed= 60/(4/3)= 
60/(4/3) = 45

There are 70 doors marked with numbers 1 to 70. There are 70 individuals marked 1 to 70.
An operation on a door is defined as changing the status of the door from open to closed or vice versa. All the doors are closed to start with. One at a time, one randomly chosen individual goes and operates the doors. The individual however operates only those doors which are a multiple of the number he/she is carrying. For example, the individual marked with number 5 operates the doors marked with 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, and 70. If every individual in the group gets one turn, then how many doors are open at the end?  Choose the correct choice from the following:
A) 0 B) 2 C) 5 D) 8 E) 10

Solution: If a door is closed at the start, it requires an odd number of people to operate to be open at the end. Only the perfect squares have an odd number of factors.   The doors which are open at the end are: 1, 4, 9, 16, 25, 36, 49, 64 for a total of 8 doors.   The answer is 8.

The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is: Choose the most appropriate option:
A) 15
B) 16
C) 18
D) 25
E) 27

Solution: Explanation :   Let the cost price of 1 article be z.   So, the cost price of 20 article = 20z ------------------------- (1)   Selling Price of 20 articles = 20z + 25% of 20z = 25z   => Selling Price of 1 article = 25z/20 = (5/4)*z   => Selling Price of x articles = (5/4)*z*x ------------------------- (2)   Given that Selling Price (S.P.) of x articles = Cost Price (C.P.) of 20 articles   => (5/4)*z*x = 20z => x = 16   Answer : 16

A feed store sells two varieties of birdseed: Brand A, which is 40% millet and 60% sunflower, and Brand B, which is 65% millet and 35% sunflower. If a customer purchases a mix of the two types of birdseed that is 50% sunflower, what percent of the mix is Brand A? Choose the most appropriate option
A) 40%
B) 45%
C) 50 %
D) 55 %
E) 60 %

Solution: Yes there is a simple method :   Consider the following method   Brand A : 40% millet and 60% sunflower   Brand B : 65% millet and 35% sunflower   Mix : 50% sunflower   Here the weighted average is 50%,   Now Brand A has 60 % sunflower, which is 10% more than the weighted average of mix = + 0.10 A --------------- I   Similarly, Brand B has 35 % sunflower, which is 15 % less than the weighted average of mix = - 0.15 B ------------ II   Now, both Brand A and Brand B are combined to give a 50% mix containing millet, so equate I and II   implies, 0.10 A = 0.15 B   Therefore A/B = 0.15/0.10 = 3/2   A : B : (A + B) = 3 : 2 : (3+2) = 3 : 2 : 5   We have to find, percent of the mix is Brand A i.e. A : (A + B) = 3 : 5 = (3 / 5) * 100= 
(3 / 5) * 100 = 60
60 %   Here is a pictorial representation :   Brand A= 60%------------------------10% or 0.10 above average, A times-----------------Total below = + 0.10 A   ----------------------------------------------------------------------------------------Average = 50% or 0.50   Brand B = 35 %--------------------------15% or 0.15 below average, B times-----------------Total above = - 0.15 B   Since the amount below the average has to equal the average above the average; therefore,   0.10 A = 0.15 B   A/B = 3/2   A:B: Total = 3:2:5   Therefore   A/Total = 3:5 = 60 %   Answer: 60 %

Choose one
A) 772 m
B) 167 m
C) 245 m
D) 267 m
E) 127 m

Solution: Speed = (45 * 5/18) m/sec = (25/2) m/sec. Time = 30 sec. Let the length of bridge be x meters. Then, (130 + X)/30 = 25/2 ==> 2(130 + X) = 750 ==> X   = 245 m.   Answer:245 m

Each of the 48 members in a high school class is required to sign up for a minimum of one and a maximum of three academic clubs. The three clubs to choose from are the poetry club, the history club, and the writing club. A total of 15 students sign up for the poetry club, 23 students for the history club, and 21 students for the writing club. If 3 students sign up for exactly two clubs, how many students sign up for all three clubs? Choose the correct choice from the following answers.
A) 3	B) 4	C) 5	D) 6	E) 7

Solution: The total number in the three clubs is 15+23+21= 
15+23+21 = 59
59.   All 48 students signed up for at least one club.   3 of those students signed up for exactly one more club.   59 - 51= 
59 - 51 = 8
8 so 4 students must have signed up for exactly three clubs.   The answer is 4.

In an examination, there were 2,000 candidates, out of which 900 candidates were girls and rest were Boys. If 32% of the boys and 32% of the girls passed, then the total percentage of failed candidates is? Choose the correct answer
A) 35.67%  B) 64.75%  C) 68.00%  D) 69.57%  E) none of these

Solution: Girls = 900, Boys = 1100   Passed = ( 32% of 1100 ) + ( 32% of 900)   = 352 + 288= 
352 + 288 = 640
640   Failed= 2000 - 640= 
2000 - 640 = 1_360
1360   Failed %= [(1360/2000) x 100]%   = 68%.   ANSWER:68.00%
