(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.

(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

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

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

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) :

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

The average number of passengers from all the given flights together

= > (1200 + 1300 + 800 + 1000 + 900 + 1100)/5

= > 6300/5 = 1260

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

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 %

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
