ANSWER:

1.Answer: Option D
Explanation:
A's 1 day's work =1;
15
B's 1 day's work =1;
20
(A + B)'s 1 day's work =(1+1)=7.
152060
(A + B)'s 4 day's work =(7x 4)=7.
6015
Therefore, Remaining work =(1 -7)=8.
1515
2.Answer: Option C
Explanation:
(A + B + C)'s 1 day's work =1,
4
A's 1 day's work =1,
16
B's 1 day's work =1.
12
Therefore C's 1 day's work =1-(1+1)=(1-7)=5.
4161244848
So, C alone can do the work in48= 93days.
55
3.Answer: Option B
Explanation:
A's 2 day's work =1x 2=1.
2010
(A + B + C)'s 1 day's work =1+1+1=6=1.
2030606010
Work done in 3 days =1+1=1.
10105
Now,1work is done in 3 days.
5
 Whole work will be done in (3 x 5) = 15 days.
4.Answer: Option B
Explanation:
Ratio of times taken by A and B = 1 : 3.
The time difference is (3 - 1) 2 days while B take 3 days and A takes 1 day.
If difference of time is 2 days, B takes 3 days.
If difference of time is 60 days, B takes3x 60= 90 days.
2
So, A takes 30 days to do the work.
A's 1 day's work =1
30
B's 1 day's work =1
90
(A + B)'s 1 day's work =1+1=4=2
30909045
 A and B together can do the work in45= 221days.
22
5.Answer: Option B
Explanation:
C's 1 day's work =1-1+1=1-7=1.
36832424
A's wages : B's wages : C's wages =1:1:1= 4 : 3 : 1.
6824
C's share (for 3 days) = Rs.3 x1x 3200= Rs. 400.
24
6.Answer: Option A
Explanation:
Let 1 man's 1 day's work = x and 1 boy's 1 day's work = y.
Then, 6x + 8y =1and 26x + 48y =1.
102
Solving these two equations, we get : x =1and y =1.
100200
(15 men + 20 boy)'s 1 day's work =15+20=1.
1002004
 15 men and 20 boys can do the work in 4 days.

7.Answer: Option C
Explanation:
A's 1 hour's work =1;
4
(B + C)'s 1 hour's work =1;
3
(A + C)'s 1 hour's work =1.
2
(A + B + C)'s 1 hour's work =(1+1)=7.
4312
B's 1 hour's work =(7-1)=1.
12212
Therefore B alone will take 12 hours to do the work.

8.Answer: Option C
Explanation:
(A + B)'s 1 day's work =1
10
C's 1 day's work =1
50
(A + B + C)'s 1 day's work =1+1=6=3. .... (i)
10505025
A's 1 day's work = (B + C)'s 1 day's work .... (ii)
From (i) and (ii), we get: 2 x (A's 1 day's work) =3
25
 A's 1 day's work =3.
50
 B's 1 day's work1-3=2=1.
10505025
So, B alone could do the work in 25 days.

9.Answer: Option C
Explanation:
Whole work is done by A in(20 x5)= 25 days.
4
Now,(1 -4)i.e.,1work is done by A and B in 3 days.
55
Whole work will be done by A and B in (3 x 5) = 15 days.
A's 1 day's work =1, (A + B)'s 1 day's work =1.
2515
Therefore B's 1 day's work =(1-1)=4=2.
152515075
So, B alone would do the work in75= 371days.
22
10.Answer: Option D
Explanation:
(P + Q + R)'s 1 hour's work =(1+1+1)=37.
81012120
Work done by P, Q and R in 2 hours =(37x 2)=37.
12060
Remaining work =(1 -37)=23.
6060
(Q + R)'s 1 hour's work =(1+1)=11.
101260
Now,11work is done by Q and R in 1 hour.
60
So,23work will be done by Q and R in(60x23)=23hours = 2 hours.
60116011
So, the work will be finished approximately 2 hours after 11 A.M., i.e., around 1 P.M.
