Directions: Read the following information to answer the question.
Explanation :
Let total money be Rs. x.
A's 1 day's wages = Rs.x/21
, B's 1 day's wages = Rs. x/28
(A + B)'s 1 day's wages = Rs.x/21+x/28 = Rs.x/12
Money is sufficient to pay the wages of both for 12 days.
Directions: Read the following information to answer the question.
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 =1/4+1/3
=7/12
(A + B + C)'s 1 hour's work =1/4+1/3=7/12
B's 1 hour's work =7/12-1/2 =1/12
B alone will take 12 hours to do the work.
Directions: Read the following information to answer the question.
Explanation :
(A + B + c)’s 1 day’s work =1/24+1/36+1/4=13/144
Work done by (A + B +C) in 4 days ={13/144}x 4 =13/36
Work done by B in 3 days ={1/36}x 3=1/12
. Remaining work =1 -13/36+1/12=5/9
(A + B)’s 1 day’s work = 1/24+1/36=5/72
Now,5/72
work was done by A and B in{72/5}x{5/9} = 8 days.
Hence, total time taken = (4 + 3 + 8) days = 15 days.
Directions: Read the following information to answer the question.
Explanation :
Son's 1 day's work =1/3-1/5=2/15
The son alone can do the work in
15/2 days.
Directions: Read the following information to answer the question.
Explanation :
Suppose B takes x days to do the work.
A takes {2 x3/4}x=3x/2
days to do it.
(A + B)'s 1 day's work = 1/18
1/x=2/3x=1/18
or x = 30
