| Saksham | Re: TCS placement previous years question papers Here as per your demand I am providing you placement paper of TCS 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 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 Explanation: Just check the options. If she bought 10 white sharpeners at Rs.6 per piece, She has spent Rs.60 already. And with the remaining Rs.40, she bought 8 brown sharpeners at 40/8 = Rs.5 which is Rs.1 less than White sharpener. The fourteen digits of a credit card are to be written in the boxes shown above. If the sum of every three consecutive digits is 18, then the value of x is : a. 3 b. cannot be determined from the given information. c. 2 d. 1 Sol : A Explanation: Let us assume right most two squares are a , b Then Sum of all the squares = 18 x 4 + a + b .......... (1) Also Sum of the squares before 7 = 18 Sum of the squares between 7, x = 18 and sum of the squares between x , 8 = 18 So Sum of the 14 squares = 18 + 7 + 18 + x + 18 + 8 + a + b (2) Equating 1 and 2 we get x = 3 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 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. 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 Ans: Explanation: This question can be solved easily by going through options. A. White sharpener total cost: Rs.5 x 10 = Rs.50. Brown sharpeners cost = Rs.4 x 8 = 32. Total cost is only Rs.82. Wrong option. B. White sharpener total cost: Rs.6 x 10 = Rs.60. Brown sharpeners cost = Rs.5 x 8 = 40. Total cost is Rs.100. Correct option. The sum of the digits of a three digit number is 17, and the sum of the squares of its digits is 109. If we subtract 495 from the number, we shall get a number consisting of the same digits written in the reverse order. Find the number. a. 773 b. 683 c. 944 d. 863 Ans: D Explanation: Check options. Sum of the squares should be equal to 109. Only Options B and D satisfying. When we subtract 495, only 863 becomes 368. |
