TCS 2013 placement new pattern questions 11

1. There are 4 boxes colored red, yellow, green and blue. If 2 boxes are selected, how many combinations are there for at least one green box or one red box to be selected?
A) 1 b) 6 c) 9 d) 5

2. The letters in the word ABUSER are permuted in all possible ways and arranged in alphabetical order then find the word at position 49 in the permuted alphabetical order?
A) ARBSEU
B) ARBESU
C) ARBSUE
D) ARBEUS
AB**** =4! = 24 ways
AE****=4! =24 ways next word is 49th so
AR**** in alphabetical order **** will be BESU
Ans is B
3. Machine A produces bolts at a uniform rate of 120 every 40 second, and Machine B produces bolts at a uniform rate of 100 every 20 seconds. If the two machines run simultaneously, how many seconds will it take for them to produce a total of 200 bolts?
Ans: Machine A produces 120/40 = 3 bolts in 1 second and machine B produces 100/20 = 5 bolts in one second.
Hence, both of them will produce 8 bolts per second. Hence, they wil take 200/8 = 25 seconds to produce 200 bolts.
4. How many prime numbers between 1 and 100 are factors of 7150?
Ans: 7, 150 = 2×52×11×13
So there are 4 distinct prime numbers that are below 100
5. In how many ways can 3 postcards can be posted in 5 postboxes?
Ans: First card can go into any of the five boxes, Second can go into any of the five boxes, Third can go into any of the five boxes = 5×5×5=125
6. What is the sum of all even integers between 99 and 301?
A. 40000
B. 20000
C. 40400
D. 20200
Answer: D
7. There are 10 stepping stones numbered 1 to 10.a fly jumps from 1st stone as follows: every minute it jumps to the 4th stone from where it started -that is from 1st it would go to 5th, from 5th it would go to 9th, from 9th it would go to 3rd, etc .where would the fly be at 60th minute if it starts at 1?
Answer 1
8. The diagonal of a square is twice the side of equilateral triangle the ratio of Area of the Triangle to the Area of Square is?
A) 3:8
B) 2:5
C) 3:6
D) 2:4
9. Kelly and Chris are moving into a new city. Both of them love books and thus packed several boxes with books. If Chris packed 60% of the total number of boxes, what was the ratio of the number of boxes Kelly packed to the number of boxes Chris packed?
If chris packs 60% of the boxes, kelly packs remaining 40% So Kelly : Chris = 40% : 60% = 2 : 3
10. There are 4 boxes colored red, yellow, green and blue. If 2 boxes are selected, how many combinations are there for at least one green box or one red box to be selected?

10) A drawer holds 4 red hats and 4 blue hats,what is the probability of getting exact three red hats or exact 3 blue hats when taking out 4 hats randomly out of the drawer and immediately returning every hat to the drawer before taking out the next.
(a)1/2(b)1/8(c)1/4(d)3/8
ANS:
probability of taking a particular hat is 1/2 ( 4/8)
Now assume we have 2 take 3 blues and 1 red
P(BBBR) = (1/2)^4
P(BBRB) = (1/2)^4
P(BRBB) = (1/2)^4
P(RBBB) = (1/2)^4
total = 4 * (1/2)^4 similarly with red thus the total is 2*4*1/16 = 8/16 = 1/2
11) 1,3,1,2.5,5,1,4,5,4,8,7,?? 12) if p(x)=ax^4 + bx^3 + cx^2 + dx + e has roots at x=1,2,3,4 and p(0)=48, what is p(5)?
(1)48 (2)24 (3)0 (4)50
13) what is the unit digit of 21^3*21^2*34^7*46^8*77^8 ?
14) The sequence is defined by A(1)=2 and A(n+1)=A(n)+2n What is the value of A(100)
(1)9902 (2)9900 (3)10100 (4)9904
15) x + y = 8 and 1/x + 1/y = 2/3 then product of x and y will be.........                                                                                                                                                       Like us on facebook:http://www.facebook.com/pages/Placement-preparation-and-Web-design/207321382695891
