f(-3) = a(-3)4 - b(-3)2 + (-3) + 5 = 81a - 9b + 2 = 2 So 81a - 9b = 0
f(3) = a(3)4 - b(3)2 + (3) + 5 = 81a - 9b + 8
Substituting the value of 81a - 9b = 0 in the above we get f(3) = 8

2. According to the stock policy of a company, each employee in the technical division is given 15 shares of the company and each employee in the recruitment division is given 10 shares. Employees belonging to both committees get 25 shares each. There are 20 employees in the company, and each one belongs to at least one division. The cost of each share is $10. If the technical division has 15 employees and the recruitment division has 10 employees, then what is the total cost of the shares given by the company?

We have to use addition formula n(A∪B) = n(A)+n(B)−n(A∩B)
20 = 15 + 10 - x
x = 5
So total shares given to only technical = 10 × 15 = 150
Shares given to only Recruitment = 5 × 10 = 50
Share given to Technical as well as recruitment people = 5 × 25 = 125
Total shares = 150 + 50 + 125 = 325.
Total value = 325 × 10 = 3250

3. .In this question, A^{B} refers to A raised to the power B.Ten tickets numbered 1, 2, 3, ..., 10. Six tickets are selected at random one of a time with replacement. The probability of the largest number appearing on the selected ticket is 7 is

\frac{(7^{6}+1)}{10^{6}}

\frac{(7^{6}+1)}{10^{6}}

\frac{(7^{6}-6^{6})}{10^{6}}

Let's first find out probability of that maximum number being any number between 1 to 7.
P(1 to 7) = (7/10) * (7/10) * (7/10) ... 6 times

Now find out probability of that maximum number being any number between 1 to 6.
P(1 to 6) = (6/10) * (6/10) * (6/10) ... 6 times

Now, probability that maximum number is exactly 7
= P(1 to 7) - P (1 to 6)
= (7^6 - 6^6) / 10^6

4. A alone can do 1/4th of the work in 2 days. B alone can do 2/3th of the work in 4 days. If all the three work together, they can complete it in 3 days so what part of the work will be completed by C in 2 days?

A can do the total work in 8 days, and B can do it in 6 days.
Let the total work be 24 units. Now capacities are
A = 24/8 = 3,
B = 24/6 = 4,
A + B + C = 24/3 = 8
So Capacity of C = 1 unit.
In two days C will do 2 units which is 2/24th part of the total work. So 1/12th part.

To find the last two digits of a product take the last two digits in each number and multiply. 01*02*03......48*49 (use onscreen calculator)
this gives 76. So 762762 = 576 So last two digits are 76

6. George and Mark can paint 720 boxes in 20 days. Mark and Harry in 24 days and Harry and George in 15 days. George works for 4 days, Mark for 8 days and Harry for 8 days. The total number of boxes painted by them is

Capacity of G + M = 720 / 20 = 36
M + H = 720 / 24 = 30
H + G = 720 / 15 = 48
Combined capacity = 2 (G + H + M) = 114
G + H + M = 114 / 2 = 57
Now capacity of G = (G+H+M) - (H + M) = 57 - 30 = 27
M = (G+H+M) - (H + G) = 57 - 48 = 9
H = (G+H+M) - (G + M) = 57 - 36 = 21
Given that G worked for 4 days, and mark for 8 and harry for 8 days
So total work by them = 4 x 27 + 8 x 9 + 8 x 21 = 348

The speed of the car is 84.96 mph

Since the car is 0.5 miles away from you, and crosses you in exactly one min, which means the other car will cover 0.5 miles more in one min than your car

The speed of your car is 55 mph or 0.916 miles per minuter

Therefore the speed of the other car is 0.916+0.5=1.416 miles per minute

Thus the speed of the other car is =1.416*60=84.96 mph

Given that A + B + C = 60 × 3 = 180
A + B + C + D = 56 × 4 = 224
Therefore, D = 44
E = 44 + 3 = 47
Given, B + C + D + E = 55 × 4 = 220
B + C + 44 + 47 = 220
⇒ B + C = 220 – 91 = 129
So A + 129 = 180 ⇒ A = 51

So x-y can be 1, 4, 9. ——– (1)
So given that 10x+y +(10y +x) = 11(x+y) is a perfect square.
So x+y be 11. Possible options are (9,2), (8,3),(7,4),(6,5) ———(2)
From the above two conditions only (6,5) satisfies the condition
Only 1 number 56 satisfies.

Let the total time taken by the cars be a and b
Let the time after which the speed is interchanged be t
For car A, 60t+90(a-t) = 420, 90a – 30t = 420 …….(1)
For car B, 90t + 60(b-t) = 420, 60b + 30t = 420 ….(2)
Using both (1) and (2), we get 90a + 60b = 840
But as a – b =1, 90a + 60(a-1) = 840.
Solving a = 6.
Substituting in equation 1, we get t = 4

The pattern is R G W B Y R G W B Y R …….
So, White bead comes at these positions 3rd, 8th, 13th, 18th…
If we take this as a arithmetic progression, then this series can be expressed as 3 + (n – 1) 5. ( From the formula for general term of AP = a + (n-1)d).
This can be expressed as 5n – 2
We check the answer options so only 68 satisfy the condition.

As she got less apples when the weight put on the right side, the left pan has more weight say w kgs.

and w+ 2 = 14a
Solving we get a = 2/9 Kgs.
So she gets, 2/(2/9) = 9 apples
