ANSWERS AND EXPLANATION ::

Answer: Option D
Explanation:
Speed=
(
60 x
5
)m/sec
=
(
50
)m/sec.
18
3

Length of the train = (Speed x Time) =
(
50
x 9
)m = 150 m

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
.
15
20
60

(A + B)'s 4 day's work =
(
7
x 4
)
=
7
.
60
15

Therefore, Remaining work =
(
1 -
7
)
=
8
.

Answer: Option B
Explanation:
Suppose A, B and C take x,
x
and
x
days respectively to finish the work.
2
3

Then,
(
1

3
)
=

 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 =
(
7
:
4
:
6
)
= 105 : 40 : 36.
2
3
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.
