222. A man can hit a target once in 3 shots.If he fires 3 shots in succession, find the probability that he will hit his target.
Answer: Option B
Explanation:Probability of hitting the target = (1 - probability of not hitting the target)
if man hits once every 3 balls,
probability of hitting = 1/3 => probability of not hitting=2/3
So, probability of not hitting the target all three times = (2/3)* (2/3)* (2/3) = 8/27
=> Probability of hitting target = (1 - 8/27) = 19/27

223.
In the given below figure, If the sum of the values along each side is equal.
Find the possible values a, b, c, d, e, and f.
Answer: Option C
Explanation:42 + a + b = 47 + e
=> a + b = 5 + e ----- (1)
by eq. (1) option a, b ruled out.
47 + e = 15 + f
=> 32 + e = f ------- (2)
Option d will be ruled out
So Option will fit in eq. (1) & (2)

224. 4 men throw a die each simultaneously. Find the probability that at least 2 people get the same number
Answer: Option B
Explanation:1-(probability of not getting same no.)=1-((6*5*4*3)/(6*6*6*6))
=(1-5/18) = 13/18
1-(probability of not getting same no.)=1-((6*5*4*3)/(6*6*6*6))
=(1-5/18) = 13/18

225. 17 X 8 m rectangular ground is surrounded by 1.5 m width path. Depth of the path is 12 cm. Gravel is filled and find the quantity of gravel required.
Answer: Option D
Explanation:Area of the rectangular ground = 17*8=136 m^2
Area of the big rectangle considering the path width = (17+2*1.5)*(8+2*1.5) = 220 m^2
Area of the path = 220−136 = 84 m^2
Gravel required = 84 m^2 * 12/100 m = 10.08 m^3

228. What is the remainder of (32^31^301) when it is divided by 9?
Answer: Option B
Explanation:32^31^301
when 31 divided by 9 gives remainder 5
5 5^2 5^3 all gives the same unit digit 5
so 31^32 gives unit digit 5
same rule applicable to 31^301
when 31 divided by 9 gives remainder 4
4 4^2 4^3 4^4 =4 6 4 6 unit place repeats for every 2 times i,e for even power its uint place is 6 and for odd its 4
as 301 is odd its unit place is 4
so 31^32^301=31^4=5^4=5

230. In how many possible ways can write 3240 as a product of 3 positive integers a,b and c.
Answer: Option A
Explanation:3240 = 23*34*51 = a*b*c
We have to distribute three 2's to a, b, c in 3+3−1C3−1 = 5C2 = 10 ways
We have to distribute four 3's to a, b, c in 3+4−1C3−1 = 6C2 = 15 ways
We have to distribute one 5 to a, b, c in 3 ways.
Total ways = 10*15*3 = 450 ways
