5. None of these

(x – 5)/15 + 6/18 = 1

(x – 5)/15 + (1/3) = 1

(x – 5 + 5)/15 = 1

X = 15 days

Total work = 12*15 = 180 work

5 days work = 12*5 = 60 work

Remaining work = 180 – 60 = 120

According to the question,

= > 120/20 = 6 days

The total no of days = 6 + 5 = 11 days

The work gets completed in 11 days

Total work = men*days

Total units of work = 15*12 = 180 units

Work done in 4 days = 15*4 = 60 units

Remaining work = 180 – 60 = 120 units

Let the number of men left after 4 days be x

According to the question,

120/10 = 15 – x

12 = 15 – x

X = 3 men

After 4 days from the start of the work, 3 men left the job.

(A + B)’s one day work = (1/12)

(B + C)’s one day work = (1/6)

(C + A)’s one day work = (1/10)

2(A + B + C)’s one day work = (1/12) + (1/6) + (1/10) = 21/60 = 7/20

(A + B + C)’s one day work = 7/40

C’s one day work = (A + B + C) – (A + B)

= > (7/40) – (1/12)

= > (84 – 40)/(40*12)

= > 44/(40*12)

= > 11/120

C can complete a whole work in = 120/11 = 10 10/11 days

Total work = (men (or) women)*days

Work equal,

(9w + 5m)*9 = (8w + 9m)*6

81w + 45m = 48w + 54m

33w = 9m

11w = 3m

m= 11/3

9w + 5m = 9w + (55/3)w = (82/3)w

5w + 9m = 5w + 33w = 38w

Women        days

(82/3)                   9

38               ?

(82/3)*9 = 38x

X = (41*3)/19 = 123/19 = 6 9/19 days

Shortcut:

Men   women        days

6        9                 69

10      8                 ?

Required days = (6*9*69)/(48 + 90) = (6*9*69)/138

= > 27 days

(Or)

6 men = 9 women

2 men = 3 women

1 men = (3/2) women

10 m + 8 w = 10*(3/2) w + 8 w = 23 w

Women        days

9                 69

23               ?

= > (9*69)/23 = 27 days

Efficiency ratio = > Q : P = 6 : 5

Days ratio = > Q : P = 5 : 6

P can do a piece of work in 18 days

6’s = 18 = > 1’s = 3

So Q can complete the work in 15 days

(1/18 + 1/15)*x = 3/4

[33/(18*15)]*x = 3/4

X = 135/22 days = 6 3/22 days

1/10 + 1/15 + 1/C = 1/5

1/C = (1/5) – (1/10 + 1/15)

(1/C) = (1/5) – (1/6) = 1/30

C can do it in 30 days.

Efficiency of A, B and C = (1/10) : (1/15) : (1/30) = 3 : 2 : 1

6’s = 1800

1’s = 300

The share of C = Rs. 300

Ganesh and Ragu’s one day work = (1/25) + (1/20) = 45/(25*20) = 9/100

Ganesh and Ragu’s 8 day work = (9/100)*8 = 18/25

Remaining work 7/25 done by Ganesh and Rohit

Ganesh and Rohit finished it in 3 ½ days

(7/25)*(Ganesh + Rohit)’s whole work = (7/2)

(Ganesh + Rohit)’s whole work = 25/2

Rohit’s one day work = (2/25) – (1/25) = 1/25

Rohit alone can complete the work in 25 days

Total work = men * days

Total work = 15*12 = 180

3 days work = 15*4 = 60

Remaining work = 180 – 60 = 120 work

Now, the total men = 15 – 3 + 8 = 20 men

Remaining work can be completed in,

= > 120/20 = 6 days

Remaining work can complete it in 6 days.
