In infosys the written test consists of 2 sections:
1) puzzle test- u have to answer 10 puzzles carrying 50 marks in 1 hour in this section try to attempt each and every question because some times they will consider those who have tried to answer the tough questions. No need to get exact answer for those questions but u should have shown some rough work to those questions that u have tried to answer those questions this will be plus point to u.
2) Test Of English Language – in this section u have to answer 45 questions in 30 minutes each question carries 1 mark all are multiple choice questions no negative marking will be present so answer all the questions first comprehension passage will be given so leave it and start with other sections after completion of all sections then switch to passage because it will take more time to answer the passage. After the completion of puzzle test they will take away question paper of puzzles but answer sheet of puzzles will be with u only so if time is left in English section u can attempt puzzles.
The questions in my test are as follows:
1) In woods there were certain birds on each tree .Number of birds on each tree are equal to total number of trees in the woods. There are 2000-2100 birds altogether in the woods. How many trees are there in the woods? ( 3 marks )
Ans) let number of birds on each tree = X = number of trees in the woods.
Then total number of birds in woods = X^ 2. = in between 2000-2100.
This number should be a perfect square there is only one number in that range which is
2025.=45^2.
So total number of trees = 45. ( 100% sure )
2)In the construction of a house these were required Designer and Painter equals Rs. 1100-----à1
Painter and Plumber equals Rs. 1700----à2
Plumber and Electrician equals Rs. 1100----à3
Electrician and Constructor equals Rs. 3300-----à4
ð By solving 7 and 2 we get pa = 900 and pl = 800.
3) A passenger train requires twice the time to overtake the freight train as it takes to cross the freight train when it is coming in opposite direction. How much faster is the passenger train in comparison with freight train? ( 3 marks) . ans) thrice.
Ans) let time taken by passenger train to cross freight (opposite direction) = t sec.=d/(sp+sf)
Then Time taken by passenger to overtake freight (same direction) = 2t sec. =d/ (sp-sf)
where total distance = d meters.
Speed of passenger = sp
Speed of freight train = sf.
So d / ( sp-sf) = 2d/(sp+sf)
ð sp = 3sf.
ð So passenger train is 3 times faster than freight train.
4) There are 5 towns - nalanda, thrilothika, rampur, solanpur and maninagar. So say N, T, S, R, M. Out of these, 4 are capitals, 3 industrial towns, two hill stations, two towns are on same longitude. Population of two cities is less than five lakhs and that of one city is 20 lakhs, also of other two cities is more than 50 lakhs. Thirlothika is an industrial town. Maninagars population is 20 lakhs. There are 4 capitals and two industrial towns. Now some data are given involving longitudes and latitudes such as, one of the hill stations do not lie in the longitude in which the harbour which is also an industrial town lies and so on. Rampur and thrilothika lies on same longitude. Solapur and Maninagar lies on same latitude like that some more data is given.
