Answer: Option D
Explanation:
A's 1 day's work =

x = 12.
So, B takes
(12/2) = 6 days to finish the work.
Answer: Option B
Explanation:
Let the
total profit be Rs. 100.
After paying to charity, A's share = Rs.

(95 x

3

)

= Rs. 57.


5

If A's
share is Rs. 57, total profit = Rs. 100.
If A's share Rs. 855, total profit =

(

100

x 855

)

= 1500.

Answer: Option D
Explanation:
Ratio of initial investments =

(

)

= 105 : 40 : 36.

2

5

Let the
initial investments be 105x, 40x and 36x.
A : B : C =

(

105x x 4 +

150

x 105x x 8

)

: (40x x 12) : (36x x 12)

100

= 1680x : 480x : 432x = 35 : 10 : 9.
Hence, B's share = Rs.

(

21600 x10/54)

= Rs. 4000.


Answer: Option D
Explanation:
Suppose B
joined for x months. Then,
Then,

(

85000 x 12

=

3

)

42500 x x

1

x =

(

85000 x 12

)

= 8.

42500 x 3

So, B
joined for 8 months.
