As you asking for the TCS Placement Paper , here I am givng you the previous year question paper of the TCS , the question paper are as following: In how many ways a team of 11 must be selected from 5 men and 11 women such that the team must comprise of not more than 3 men? a. 1565 b. 1243 c. 2256 d. 2456 Ans: C Explanation; The team may consist of 0 men + 11 women, 1 men + 10 women, 2 men + 9 women, or 3 men + 8 women. So Number of ways are = 11C11+5C1×11C10+5C2×11C9+5C3×11C8 = 2256 3. Given that 0 < a < b < c < d, which of the following the largest ? a.(c+d) / (a+b) b.(a+d) / (b+c) c.(b+c) / (a+d) d.(b+d) / (a+c) Sol: A Explanation: Take a = 1, b = 2, c = 3, d = 4. option A is clearly true. 4. Eesha bought 18 sharpeners for Rs.100. She paid 1 rupee more for each white sharpener than for each brown sharpener. What is the price of a white sharpener and how many white sharpener did she buy ? a. Rs.5, 10 b. Rs.6, 10 c. Rs.5, 8 d. Rs.6, 8 Sol: B 6. Four people each roll a four die once. Find the probability that at least two people will roll the same number ? a. 5/18 b. 13/18 c. None of the given choices d. 1295/1296 Sol: B Explanation: The number of ways of rolling a dice where no two numbers probability that no one rolls the same number = 6 x 5 x 4 x 3 Now total possibilities of rolling a dice = 64 The probability that a no one gets the same number = 6×5×4×364=518 So the probability that at least two people gets same number = 1−518=1318 7. Jake can dig a well in 16 days. Paul can dig the same well in 24 days. Jake, Paul and Hari together dig the well in 8 days. Hari alone can dig the well in a. 96 days b. 48 days c. 32 days d. 24 days Sol: Explanation: Simple one. Let the total work to be done is 48 meters. Now Jake can dig 3 mts, Paul can dig 2 mts a day. Now all of them combined dug in 8 days so per day they dug 48/8 = 6 mts. So Of these 8 mts, Hari capacity is 1 mt. So he takes 48 /1 = 48 days to complete the digging job. rest of the questions you may find in the file given below: TCS placement paper
