Answers :
1) Answer: a)
(A + B + C)’s one hour work = (1/9)
(A + B + C)’s 4 hour work = (4/9)
Remaining work = 1 – (4/9) = (5/9)
(5/9)*(A + B)’s whole work = 15/2
(A + B)’s whole work = 27/2 days
C’s one hour work = (1/9) – (2/27) = 1/27 hours
C alone can fill the tank in 27 hours.
2) Answer: d)
(4/9) of a number = (5/6) of another number
(4/9)*x = (5/6)*y
(x/y) = (5/6)*(9/4) = 15/8
X : y = 15 : 8
23’s = 92 = > 1’s = 4
The numbers are = 15*4 and 8*4 = 60 and 32
3) Answer: a)
The share of P, Q and R
= > [4x*3 + (4x + 15000)*9]: [7*12]: [9x*7 + (9x – 8000)*5]
= > [12x + 36x + 135000]: [84x]: [63x + 45x – 40000]
According to the question,
= > 48x + 135000 + 84x + 108x – 40000 = 229400
= > 240x + 95000 = 229400
= > 240x = 134400
= > x = 560
The share of Q = 84x = Rs. 47040
4) Answer: d)
P(E) = n(E)/n(S)
n(S) = 17C4
Probability of getting a ball of different colours
P(E) = (5C1 and 3C1 and 4C1 and 5C1) / 17C4
P(E) = 15/119
Required probability = 15/119
5) Answer: a)
The difference between simple interest and compound interest on certain time for 2 years is,
= > Diff = Sum*(r/100)2
= > Diff = 75000*(12/100)2
= > Diff = 75000*(3/25)2
= > Diff = 75000*(9/625) = Rs. 1080
Direction (6-10) :
6) Answer: c)
The number of passengers from flight P and R together doesn’t go to the country of Venezuela and Columbia
= > (1200 + 800)*(61/100)
= > 1220
The total number of passengers from flight T = 900
Required difference = 1220 – 900 = 320
7) Answer: b)
The average number of passengers from all the given flights together
= > (1200 + 1300 + 800 + 1000 + 900 + 1100)/5
= > 6300/5 = 1260
8) Answer: a)
The total number of male passengers from flight Q and S together
= > 1300*(36/65) + 1000*(27/50)
= > 720 + 540 = 1260
The total number of female passengers from flight Q and S together
= > 1300*(29/65) + 1000*(23/50)
= > 580 + 460 = 1040
Required ratio = 1260: 1040 = 63: 52
9) Answer: c)
Total number of passengers from flight P, R and T together
= > 1200 + 800 + 900 = 2900
Total number of passengers from flight Q, S and U together
= > 1300 + 1000 + 1100 = 3400
Required % = (2900/3400)*100 = 85 %
10) Answer: e)
The average number of passengers from flight P and S together in the year 2019
= > [1200*(120/100) + 1000*(120/100)]/2
= > (1440 + 1200)/2 = 1320
The average number of passengers from flight Q and T together in the year 2019
= > [(1300*(120/100) + 900*(120/100)]/2
= > (1560 + 1080)/2 = 1320
Required difference = 1320 – 1320 = 0
