x ------- 9
(x + 10) ---- 6
x * 9 = (x + 10)6
x = 20.

 

A`s one day work is =1/5. 1/5*30=6
5+6=11/30
B`s one day work is =1/6. 1/6*30=5
One day work of A and B is =11/30
So they will complete the work in 30/11 days.

As per question, A do twice the work as done by B.
So A:B = 2:1
Also (A+B) one day work = 1/18
To get days in which B will finish the work, lets calculate work done by B in 1 day =
=(1/18*1/3)=1/54
[Please note we multiplied by 1/3 as per B share and total of ratio is 1/3]
So B will finish the work in 54 days

 

That is, 1 work done = 12 × 8 × 10
Then,   96× 10 = ? × 15 × 8
(i.e. No. of men required) = 12 × 8 × 10/15× 10 = 8 days.

1 minute's work of both the leakage = 1/9+1/6 = 5/18
So, both the leakage will empty the tank in 18/5 min

A's 1 day's work = 1/16
B's 1 day's work = 1/20
(A + B + C)'s 1 day's work = 1/10
=> C's 1 day's work = 1/10-1/16+1/20 = 1/80
So, C can paint the house in 80 days.

Suppose A, B and C take x, x/2 and x/3 days respectively to finish the work.
Then, 1/x + 2/x + 3/x = 1/2
6/x = 1/2
x = 12.
So, B takes (12/2) = 6 days to finish the work.

Adam can do 1/15 of the job per day
Eve can do 1/20 of the job per day
If they work together they can do 7/60 of the work together
Remaining job 1 - 7/60 = 32/60 = 8/15

Therefore A\'s one day’s work = 1/30

B\' s one day’s work = 1/40

(A+B)\'s one day’s work = 1/30+1/40

4+3/120=7/120

Number of days required for A and B to finish the work = 17/120=17/7days

When A runs 5 rounds, B runs 4 rounds (ratio of speeds)
A passes B each time A has run 5 rounds or 5 x 1/4 = 5/4km. = 1 1/4km
1 1/4km is contained in 4 km 3 times. Hence A passes B thrice.
