 Count the number of crows in the city2 AnswersHere i actually propose a method to calculate the number of crows.No smart ass answers like the one above!...Let us assume the number of crows is N during the day,then at night the number of crows in city will be somewhat close to N since if x crows left the city then its fair enough to assume that x entered the city,thus there are N at night.All we need to do then is to find shelter for crows to bunk at night.Its well known that crows rest in trees,especially their branches(wonder the crap comes from when you park you car under a tree??).Let on a average Y such crows bunk in one tree,all one needs to do is find the number of such fairly average sized trees,which is again simple for cities as there are fewer trees per M sqkm(100-150),and then multiply that with the total area of the city. Thus it goes as follows:One tree has Y crows, a single sqkm has M such trees,multiplies by total area which is A sqkm Thus N=A*M*Y5276. If interviewer says.. I counted and found it is more.. then tell extra came from other city to meet family, and if he says he found less... then say some of them have gone for vacation

 I buy 100 eggs everyday and 2 of them turn out to be spoiled every time. Today also i bought 100 eggs, how many of them will be spoiled this time?4 AnswersThey will be just looking for your analytic skill. The numerical answer doesn't matter.can be any no......as the current probability doesnt depend on the previous probability........The probability would be N. We can't predict the future unless it come to present. We can just assume. And we can create the data on basis of previous records. But it will be only assumption. So the answer would be on basis of assumptions on previous records it would be 2. But of you are looking for right answer then we have to look on the each eggs so the probability would be NShow more responsesis this site a crap or something...

 Please estimate the number of paint cans required to paint the entire fleet of Spice Jet.3 AnswersAnswer is one. Since, the condition painting the paint without leaving any part of the plane is not used here.'Entire fleet' implies 'entire plane' as well ! This is not the approach supposed to be used to solve the problem !We can zero in on the answer by the following steps 1. Number of planes in the Spice Jet fleet : ~30 2. Model of a spicejet flight to estimate size : 200 seater 3. Split the Parts of the plane and measure area a.fuselage : ~14 ft wide, 100 ft long (excluding tapering effect) --> Circumference = 2*Pi*7 = 44 ft X 100 ft = 4400 sqft b. Wing Span : Almost equal to the length : ~50 ft each , Base width : 25 ft --> Area = (0.5 * 25 * 50) * 2 sides * 2 wings = 2500 sq ft c.Tail : 30 ft height, 20 ft base --> Area : (0.5 * 30 * 20 ) * 2 sides = 600 sq ft d. Tail Wings : 20 ft Length, 10 ft base --> Area : (0.5 * 20 * 10) * 2 sides * 2 wings = 400 sq ft e.100 sq ft for engine and wheels Total 8000 sq ft 4. Assume each can of paint covers 100 sq ft of area. Each plane requires 80 cans of paint 5. Fleet would need 80 * 30 = 2400 Cans of paint Assumptions :

 there is a problem of oil freezing in pipelines in alaska. what are your solutions to prevent/ control this?2 Answersinsulating pipelines with steam, passing crude at higher temperatures, additives to prevent freezing etc.As a BA, the solution must come from the SME's. My job is to elicit a solution through a requirements gathering approach. One of the elements of that approach is to start with understanding a) how things are done currently, b) What are the reasons that existing techniques are not sufficient c) Has the SME any thoughts on what might be a good solution?

 There are 27 identical balls with only one ball having a different weight from others. Give the minimum possible steps to identify that mis-weighted ball.2 Answersans:3 step1:divide it into 3 groups of 9 then weigh the two groups toghether,if both are equal then by default the 3rd one weighs the more or less. So we will get a group that has different weight. step2:now divide it again,3 groups of 3, repeat the same procedure. step3:now there are 3 balls left,repeat the above procedure to get the different weighted ball so in all minimum 3 steps required.ans:3 step1:divide it into 3 groups of 9 then weigh the two groups toghether,if both are equal then by default the 3rd one weighs the more or less.
