1.(2)
Mohan and sohan do work in = 12 days
sohan do work in = 28 days
so Mohan do work alone = 1/12 – 1/28 = 1/21 of work
mohan’s alone time = 1/1/21 = 21 days

2.(3)
Mary’s efficiency = 10%
Maurice’s efficiency = 6.66%
Total = 16.66%
Work will be completed in 6 days
Work done in 3 days = 50%
remaining = 50%
Mary will complete the remaining in = 50/10 = 5
Total = 5+3 = 8 days

3.(1)
4.(4)
Let alone time of Kaberi = x,
then alone time of kanti = x/2 and
kalpana = x/3
Kaberi’s 1 day work + kanti’s 1 day work+ kalpana’s 1 day work
=> 1/x + 1/x/2 + 1/x/3 = 1
=> x = 6
so alone time of Kaberi = 6 days
alone time of Kanti = 3 days
alone time of Kalpana = 2 days

5. (1)
6. (4)
p’s 1 day work = 1/12
Q is 60% more fast then p, so Q’s 1 day work = 1.6*1/12 = 2/15
Q can finish alone in 1/2/15 = 15/2 = 7(1/2) days

7. (4)
8. (2)
Since Ramesh is thrice as good a workman as Bipin .So ,if Bipin completes in 3t days,then Ramesh does in t days
so 3t – t = 40
=> t = 20
=> Bipin takes 60 days and Ramesh takes 20 days (Ramesh+Bipin)’s 1 day work
=> 1/60 + 1/20 = 1/15 = 15 days.

9.(1)
10.(1)
(5M +2W)’s 1 day work = (1M +1W)’s 4 day work
5M + 2W = 4(1M+1W)
5M + 2W = 4M + 4W
1M + 2W
M/W = 2/1
