The ratio material cost and labor cost in a small construction project is 3:1. If the labor cost went up by 20% and material cost witnessed an avenge increase of 15%, what will be the new ratio of labor cost and material cost?
Let us take material cost and labor cost as Rs 300 and Rs 100 respectively. Since labor cost went up by 20%, the revised labor cost is Rs 120. The revised material cost due to 15% increase is Rs (300+15% of 300) = 345. The ratio of labor cost and material cost is 120: 345 or 8: 23 i.e. (b)
A monkey is trying to reach the top of a tree. He climbs 3 feet in a minute but slides down by 1.5 feet after each climb. If he reaches the top of the tree in 58 minutes, then the maximum possible height of the tree is ____ feets.
You have to carefully observe the point that in the last minute, we DO NOT have to consider the sliding down of the monkey since the question states that the monkey reaches the top of the tree.Out of 58 minutes, the climb by monkey in 58th minute is 3 feet whereas for each of his earlier climbs, the monkey covers a net distance of 31.5=1.5 feet.We can work out the maximum possible height of the tree as 1.5×57+3=85.5+3=88.5 feet
Direction: Read the sentence to find out whether there is any error in it. The error, if any, will be in one part of the sentence. If the given sentence is correct as it is, mark E i.e. No error as the answer. Ignore the errors of punctuation, if any.The misuse of drugs and alcohol were seen as very damaging/ to the society, chiefly because it often promoted/ violent crimes and antisocial behavior; while also/ causing illhealth, poverty and family breakdown.
The error lies in the first part of the sentence where the verb ‘were’ is incorrect and needs to be replaced with ‘was’ as the subject "misuse" is singular. To make the subject and the verb agree it should read as:’The misuse of drugs and alcohol was seen as..’
An event A is considered to be rolling a fair dice .If 10 dice are rolled each of which are independent, find the probability that the sum obtained on the faces is between 30 and 40 both inclusive.
Given: N(1.0184) = 0.84 , which is value of normal distribution for X = 1.018
Let Xi denote the ith dice.
Since events are independent,
E(xi) = 7/2
V(xi) = 350/12
According to Central Limit Theorem,
P(30≤ X ≤40) = P(30 – 35 ≤ X – 35 ≤ 4035)
Its converting to standard form, X – E[X] / std, where std is standard deviation.
Thus,
P = 2N(1.0184) – 1
= 0.69
Which of the given option is most appropriate in the context of the word in bold letters in the given sentence.The reason there is no exodus towards banks in general for new project funding is their relatively less experience in project appraisal.

Broke down = suddenly ceased or stopped to function (of a machine or motor vehicle)
As per the context of the sentence, the correct phrasal verb is "broke down".
Chinnaswamy is driving to pick up his son from school on a Saturday which is a half day. On his way to school, he crossed a church which is 1/5th of the way to school at 9:50 hours and exactly 10 minutes later, he went past a temple which is 1/3rd of the way to school. The time after 10:00 hours at which he reaches his son’s school is ____ minutes.
Since we are given time to cross a point which is 1/5th of the way and 1/3rd of the way, we can rewrite them as 3/15th and 5/15th of the way which implies that 2/15th of the way was covered in 10 minutes.
This means that the entire route was covered in 10 × 15/2 = 75 minutes (each 1/15th part is covered in 75/15 = 5 minutes) leading to time of arrival at school as 9:50 – 15 + 75 = 10:50 hours.
In the following question, out of the four alternatives, select the word similar in meaning to the given word.Literal
Literal = line for line, letter to letter

Draw the process state transition diagram of an OS in which (i) each process is in one of the five states: created, ready, running, blocked (i.e. sleep or wait), or terminated, and (ii) only nonpreemptive scheduling is used by the OS. Label the transitions appropriately.
The following typical process states are possible on computer systems of all kinds. In most of these states, processes are "stored" on main memory.
Created: When a process is first created, it occupies the "created" or "new" state. Ready and waiting: A "ready" or "waiting" process has been loaded into main memory and is awaiting execution on a CPU. There may be many "ready" processes at any one point of the system's execution.
Running: A process moves into the running state when it is chosen for execution. The process's instructions are executed by one of the CPUs (or cores) of the system. There is at most one running process per CPU or core. A process can run in either of the two modes, namely kernel mode or user mode.
Kernel mode : Processes in kernel mode can access both: kernel and user addresses.Kernel mode allows unrestricted access to hardware including execution of privileged instructions.
User mode : Processes in user mode can access their own instructions and data but not kernel instructions and data .access to any hardware device is allowed.
Blocked : A process that is blocked on some event (such as I/O operation completion or a signal), may be blocked due to various reasons, such as exhausting its CPU time allocation or waiting for an event to occur.
Terminated : A process may be terminated, either from the "running" state by completing its execution or by explicitly being killed

Initially a priority queue had 5 elements and it is being implemented as MaxHeap. Let’s say the level order traversal of the heap is: 30, 18, 17, 12, 11. Now two more elements are inserted into the heap i.e. 10 and 19 in the same order. The level order traversal of the heap after the insertion is:
So, the insertion is followed in the same order, hence, we will insert 10 first which doesn’t effect the tree. Now, we insert 19. After insertion of 19 max_heapify founds an error in the node 17 → 11, 17 → 19. So, 19 is send up and 17 is brought down. After that the level order traversal changes to 30, 18, 19, 12, 11, 10, 17

After 1st pass, distances are c 3. e 2. e is minimum, so shortest distance toe is 2 After 2nd pass, distances are c 3, f 0. f is minimum, so shortest distance t of is 0 After 3rd pass, distances are c 3, g 3. Both are same, let us take g. so shortest distance to g is 3. After 4th pass, distances are c 3, h 5 c is minimum, so shortest distance to c is 3 After 5th pass, distances are h 2 h is minimum, so shortest distance to h is 2.
Consider a company, where a team is having seven different tasks. We have to complete these tasks with only four employees. Among these task, one task is tougher than other tasks. Similarly, we have one employee that is better than among other employees. In how many ways we can seven different tasks be assigned to four different employees so that each employee is assigned at least one task and the most difficult task is assigned to the best employee is _____________?
As seen in the above image, best job is already assign to the best employee. Now we have 6 remaining job, that we need to assign to 4 employee. why 4?
Because best employee still can do other jobs.
Let N(e2) denotes no. of function where e2 is not assigned to any job.
this will represent the no. of functions where e2, e3 and e4 is assign to any job.
why we are not counting best employee for this counting because best employee is always assign to the job

Which is the correct option that shows minimization of figure shown?
In this, we see that on b state, state 2 will go to state 1 with state 3 going to state 4 which further will go as state 1 and state 4 are in different set. Further, states 2 and 3 are different from each other. As state 4 goes to state 4 with state 3 goes to state 5 and state 4 which lies in different sets, hence state 3 and state 4 gets separated from each other. Further, state 2 goes to state 1 while state 4 goes to state 4 and to state 1. Further it is seen that state 2 and state 4 are separated from each other.
Further it is observed that as state 1 goes to state 3 placed on node a and further to state 2 which lies on node b as shown, hence the minimized DFA transitions are added from state 1 to state 3 on a while state 1 to state 2 on node b. Further as state 2 goes to state 1 on node b and state 3 goes to state 1 on node a, so minimized DFA transitions adds from state 2 to state 1 on node b and further state 3 to state 1 on node a.

There are x number of identical balls which are to be placed in y number of distinct buckets. If x>= ky (where k is a natural number greater than equal to 1), then in how many ways can you place the balls in the bucket with the condition that each bucket should contain at least k balls?
As there have to be at least k balls in each bag, so firstly put k balls in each bag i.e k*y balls. Balls remaining: xky
We can now apply balls and sticks method.
y bags= y variables, they need to equal to xk*y, no restrictions on how many balls in each bag. We can make a equation out of this:
a1 + a2 + ... + ay = x k*y
On solving it we get our answer: (xky+y1) C (y1)
