ans:4
On 1 jully, the total number of employee decreased by 10%. Without any change in the remaining employees, the avg employee salary was 10% more after the decrease in number of employees that before decrease. The total of all combined salary of all employees after 1 jully was what percent of that before 1jully
1. 90%
2.99%
3.100%
4. 101 %
5. 110%
ans:2
#1
Since n is a multiple of 5 and p and q are prime, then either p or q could be 5. Thus when both p and q are squared, it would definitely be a multiple of 25. As shown in option 4
#2
Let old average salary be x
Let new average salary be y
Since we are using percentages, assume number of old employees are 100. 10 were fired. So there are 90 left.
Given new average = 110% of old average.
=> y=1.1x
Required ratio is
(no of new employees * new average salary) / (no of old employees *old average salary)
Thus required ratio is 90y / 100x
Substituting y = 1.1x
(90 * 1.1x) / (100x) => 0.99
In percentage this is 99%

Is CD > BC ?
(1) AD = 20
(2) AB = CD
A Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D EACH Statement ALONE is sufficient.
E Statements (1) and (2) TOGETHER are NOT sufficient.
Has to be E, the figure cannot be taken as a precise point of reference.
Assume, AB=CD=3
then BC=14
implies BC>CD,
conversely AB=CD=9, then BC=2
implies CD>BC

Is CD > BC ?
(1) AD = 20
(2) AB = CD
A Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D EACH Statement ALONE is sufficient.
E Statements (1) and (2) TOGETHER are NOT sufficient.
Answer is E,
By first using 1 option we knew only ad,but we dont know about cd & bc , so it is incorrect
2 option ab=cd,u can take n no of values ab =cd=10,20,30......but we dont know individually values of a,b,c,d. hence it is not correct
By using both ad=10,hence ab=10 & cd =10.here we also we dont wat the values of a,b,c,d .so it is also in correct
Hence Answer should be E
by using 1 st option we can say the answer out of 9 balls removed from box the ration is 2:1, the stem stated it self as initial ratio is 2:1 hence Balls Red 7 And Blue balls 3 r removed from the box , then only ratio is 2:1
By using 2 statement we cannot say answer because out 6 balls there was 4 red and 2 bule . and remaining balls may be red or blue . so we cannt say how many red balls r left in the jar itself
Option is 1
A lighting store is stocked with 410 fixtures. Some of them are floor lamps and the rest are table lamps. If 5% of the floor lamps and 30% of the table lamps are imported, what is the least possible number of imported lamps stocked at the store?

23.
Table lamps = T
Floor Lamps = F
Imported Lamps = I
Given T+F = 410
I = 0.05 T + 0.3 F
In order for lamps to be minimum, T should be maximized. However, 0.3 F needs to be a whole number. Thus lowest possible value for F = 10.
Implies T = 400 (From equation 1)
Implies I = 0.05 * 400 + 0.3 * 10 = 23
A jar contains 30 marbles, of which 20 are red and 10 are blue. If 9 of the marbles are removed, how many of the marbles left in the jar are red?
(1) Of the marbles removed, the ratio of the number of red ones to the number of blue ones is 2 : 1.
(2) Of the first 6 marbles removed, 4 are red.
A Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D EACH Statement ALONE is sufficient.
E Statements (1) and (2) TOGETHER are NOT sufficient.
by using first statement we can tell the answer.but second is not
hence option is 1

Hi i need help in this
1.in how many ways can 225 be expressed as a product of 2 +ve integers..?
Hi i need help in this
1.in how many ways can 225 be expressed as a product of 2 +ve integers..?
Is the ans to this Q 5?
225 = 5^2 * 3^2 ===? No.of ways to write as product of 2 +ve nos is 4 (2*2)
225*1 is another way.So we get 4+1 = 5 ways.

OA is given 4 don know how..?
vishal das SaysOA is given 4 don know how..?
OA might have missed 225*1 or the question shud be product of 2 diff integers .Here are 5 ways to write 225 as product of 2 + integers:
25*9
15*15
125*3
5*45
225*1

Q. A project scheduled to be carried out over a single fiscal year has a budget of $12,600, divided into 12 equal monthly allocations. At the end of the fourth month of that fiscal year, the total amount actually spent on the project was $4580. By how much was the project over its budget?
Ans. (Short Method 
)
We know the actual amount spent during four month i.e. $4580. So we need to calculate budget amount for the same period.
Budget amount per month = 12600/12 = $1050
So, budget amount for four months = 1050*4 = $4200 
(We have a budget of $4200 for these four months and have spent $4580. Ofcourse, It's a Indian situation:-o)
Amount over budget = 4580 - 4200 = $380
This is the answer.........

Hello,
Q. Rectangular Floors X and Y have equal area. If floor X is 12 feet by 18 feet and Floor Y is 9 feet wide, What is the length of Floor Y, in feet?
Options:
A. 13.5 B. 18 C. 18.75 D. 21 E. 24
(you guys are thinking, what a 'F' problem )
Let's check my method. we will solve it with options.
Ans. Area of Floor X = Area of Floor Y
means Length*Width of X = Length*Width of Y
See carefully, Area of Floor X is Integer and 6 is the unit digit. Am i right? 
Option A and C eliminated because Answer will be in decimals. Remain with B,D and E
Option B has unit digit of 2 and Option D has unit digit of 9 So These are also eliminated.
So Option E is the answer. Now you can check it with your method. 
(12*18 = 9*24)
