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

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
