Aptitude Questions wipro Campus Placement 2

Ans :16/3 inches
Explanation : Let x be the amount of increase. The volume will increase by the same amount if the radius increased or the height is increased. So, the effect on increasing height is equal to the effect on increasing the radius.
i.e., (22/7)*8*8*(3+x) = (22/7)*(8+x)*(8+x)*3
Solving the quadratic equation we get the x = 0 or 16/3. The possible increase would be by 16/3 inches.

A man bought a horse and a cart. If he sold the horse at 10 % loss and the cart at 20 % gain, he would not lose anything; but if he sold the horse at 5% loss and the cart at 5% gain, he would lose Rs. 10 in the bargain. The amount paid by him was Rs.- _______ for the horse and Rs.________ for the cart.
Ans :Cost price of horse: Rs. 400 &
Cost price of cart: Rs. 200
Explanation:
Let x be the cost of horse & y be the cost of the cart.
10 % of loss in selling horse = 20 % of gain in selling the cart
Therefore (10 / 100) * x = (20 * 100) * y
x = 2y ———–(1)
5 % of loss in selling the horse is 10 more than the 5 % gain in selling the
cart.
Therefore (5 / 100) * x - 10 = (5 / 100) * y
5x - 1000 = 5y
Substituting (1)
10y - 1000 = 5y
5y = 1000
y = 200
x = 400 from (1).

Five farmers have 7, 9, 11, 13 & 14 apple trees, respectively in their orchards. Last year, each of them discovered that every tree in their own orchard bore exactly the same number of apples. Further, if the third farmer gives one apple to the first, and the fifth gives three to each of the second and the fourth, they would all have exactly the same number of apples. What were the yields per tree in the orchards of the third and fourth farmers?
Ans :11 & 9 apples per tree.
Explanation:
Let a, b, c, d & e be the total number of apples bored per year in A, B, C, D &
E 's orchard. Given that a + 1 = b + 3 = c - 1 = d + 3 = e - 6
But the question is to find the number of apples bored per tree in C and D 's orchard.
If is enough to consider c - 1 = d + 3.
Since the number of trees in C's orchard is 11 and that of D's orchard is 13.
Let x and y be the number of apples bored per tree in C & d 's orchard respectively.
Therefore 11 x - 1 = 13 y + 3
By trial and error method, we get the value for x and y as 11 and 9.

A man bought a horse and a cart. If he sold the horse at 10 % loss and the cart at 20 % gain, he would not lose anything; but if he sold the horse at 5% loss and the cart at 5% gain, he would lose Rs. 10 in the bargain. The amount paid by him was Rs.- _______ for the horse and Rs.________ for the cart.
Ans :Cost price of horse = Rs. 400 & the cost price of cart = 200.
Explanation:-
Let x be the cost price of the horse and y be the cost price of the cart.
In the first sale there is no loss or profit. (i.e.) The loss obtained is equal to the gain.
Therefore (10/100) * x = (20/100) * y
X = 2 * y —————–(1)
In the second sale, he lost Rs. 10. (i.e.) The loss is greater than the profit by Rs. 10.
Therefore (5 / 100) * x = (5 / 100) * y + 10 ——-(2)
Substituting (1) in (2) we get
(10 / 100) * y = (5 / 100) * y + 10
(5 / 100) * y = 10
y = 200
From (1) 2 * 200 = x = 400.

A contractor agreeing to finish a work in 150 days, employed 75 men each working 8 hours daily. After 90 days, only 2/7 of the work was completed. Increasing the number of men by ________ each working now for 10 hours daily, the work can be completed in time.
Ans :150 men.
Explanation:
One day's work = 2 / (7 * 90)
One hour's work = 2 / (7 * 90 *
One man's work = 2 / (7 * 90 * 8 * 75)
The remaining work (5/7) has to be completed within 60 days, because the
total number of days allotted for the project is 150 days.
So we get the equation
(2 * 10 * x * 60) / (7 * 90 * 8 * 75) = 5/7 where x is the number of men
working after the 90th day.
We get x = 225
Since we have 75 men already, it is enough to add only 150 men..

Ans :7 days
Explanation:
The equation portraying the given problem is:
10 * x - 2 * (30 - x) = 216 where x is the number of working days.
Solving this we get x = 23
Number of days he was absent was 7 (30-23) days..

It was calculated that 75 men could complete a piece of work in 20 days. When work was scheduled to commence, it was found necessary to send 25 men to another project. How much longer will it take to complete the work?
Ans :30 days.
Explanation:
Before:
One day work = 1 / 20
One man's one day work = 1 / ( 20 * 75)
Now:
No. Of workers = 50
One day work = 50 * 1 / ( 20 * 75)
The total no. of days required to complete the work = (75 * 20) / 50 = 30

A man bought a horse and a cart. If he sold the horse at 10 % loss and the cart at 20 % gain, he would not lose anything; but if he sold the horse at 5% loss and the cart at 5% gain, he would lose Rs. 10 in the bargain. The amount paid by him was Rs.- _______ for the horse and Rs.________ for the cart.
Ans :Cost price of horse = Rs. 400 & the cost price of cart = 200.
Explanation:-
Let x be the cost price of the horse and y be the cost price of the cart.
In the first sale there is no loss or profit. (i.e.) The loss obtained is equal to the gain.
Therefore (10/100) * x = (20/100) * y
X = 2 * y —————–(1)
In the second sale, he lost Rs. 10. (i.e.) The loss is greater than the profit by Rs. 10.
Therefore (5 / 100) * x = (5 / 100) * y + 10 ——-(2)
Substituting (1) in (2) we get
(10 / 100) * y = (5 / 100) * y + 10
(5 / 100) * y = 10
y = 200
From (1) 2 * 200 = x = 400.

A cylindrical container has a radius of eight inches with a height of three inches. Compute how many inches should be added to either the radius or height to give the same increase in
volume?
Ans :16/3 inches
Explanation : Let x be the amount of increase. The volume will increase by the same amount if the radius increased or the height is increased. So, the effect on increasing height is equal to the effect on increasing the radius.
i.e., (22/7)*8*8*(3+x) = (22/7)*(8+x)*(8+x)*3
Solving the quadratic equation we get the x = 0 or 16/3. The possible increase would be by 16/3 inches.

WIPRO Latest INTERVIEW RAJAHMUNDRY

Sec A: Verbal: 15ques. It was very easy. The first five questions were fill in the blanks with prepositions. One question was on identifying the missing punctuation mark. One question was on active and passive voice. And one question was on direct and indirect speech. One question was picking out the odd man out from the words" skulk, lurk, malinger, correct". A question was given on filling up of correct word, etc.
I dint prepare anything fr English but I managed it.

Sec B: Analytical + Quant: 15 ques. It was very difficult. None of them are frm R.S.Agarwal. We have to use our common sense to do them. One question was on pendulum length and time period. The proportionality was mentioned. And to my shock there were three paragraphs in this section. We asked to find out the conclusions. And I can remember one question. There was a wall of length 40m.Also a ladder of length 9m.The question was how much length ladder a man should use to reach the top of wall. Also a series was given. I don't remember the series. Not even a single question was given on time nd wrk, time nd distance, and pipes nd cisterns.

Sec C: Technical: 20 ques. It was easy because I m frm CSE. Many of the questions were from C, pointers, CPP, DBMS, OS. Frm UNIX there were 3 questions. One of them was what is the command to remove all the files, directories etc? The options were "1.rm 2.rm * 3.rm *.* 4.none". Two ques frm Computer Networks. One of them was to fill up blanks in various layers of OSI model.
It has sectional cutoff, nd time was 60 mins. no negative markin was thre. But i attempted only those on wch i was confident. I attempted english-12, aptitude-13, technical-16.

Round 2: Tech Interview

After one nd a half hr, results came nd I was there in d shortlisted candidates. I entered and sat there for my turn to come. thre were many sitting out of which one person called me and interviewed me. He was the coolest man. He asked me to sit down. Then he asked me for my resume, I gave to him. He went thru my resume nd asked me abt my seminars which I had given. I explaind him. Then he asked abt my family background. He asked me one question frm java i.e about the files which we import. And asked abt function overloading. Frm unix he asked me the command to list al the files. He asked abt UML (Unified Modeling Language). He asked what is UML. I expained it as we r havin it in our 3rd year 2nd sem. He asked me to explain software engineering. Also software life cycle. I have mentioned 8086 in my resume. He asked me one question on it. He asked me how can u lead a team when others r not listening ur words. I answered him "Such a situation will never happen if I am the team lead". I was able to answer all d ques well. After that, he gave me the HR form. It meant that ur tech intw was clear. I was thre in abt 25 mins.
