A, B and C enter into a partnership and their shares are in the ratio 1/2:1/3:1/4. After 2 months, A withdraws half of his capital and after 10 months, a profit of Rs. 378 is divided among them. What is B’s share?
ARs .129
BRs. 144
CRs. 156
DRs. 168
Answer: Option B
Explanation:Ratio of investment = 1/2 : 1/3 : 1/4,
taking lcm of (2,3,4) and divide by this ratio's we get 6 : 4 : 3,
we have to assume there initial investment is 6x, 4x and 3x
now we can write A : B : C = (6x * 2 + 3x*10) : (4x *12) : (3x*12) after doing calculation we got
= 42:48:36 more simplify it
= 7:8:6
now we need to calc B'share = (8/21) * 378 = 144

A train traveling at 42 kms/ hr passes a cyclist going in the same direction in 9 secs. If the cyclist had been going in the opposite direction, the train would have passed him in 5 secs. Find the length of the train.
A75 meters
B60 meters
C80 meters
D90 meters
Answer: Option A
Explanation:Let the length of the train be x meter and the speed of the cyclist is y m/s
Now when the train and the cyclist are in the same direction, the relative speed is :(35/3-y)m/s
[converting 42km/h to m/s-35/3m/s]
Now distance/relative speed =9 seconds
Substituting the values, we get x+9y.....................(1)
Similarly calculate the relative speed when they are in the opposite direction
The relative speed is (35/3+y)
Now distance/relative speed is equivalent to 5 seconds
Substituting the values, we get the equation
3x-15y=175.................................(2)
Solving (1) and (2), we get x=75 meters

Divide 45 into four parts such that when 2 is added to the first part, 2 is subtracted from the second part, 2 is multiplied by the third part and the fourth part is divided by two, all result in the same number.
A8, 12, 5, 20
B6,10,15,11
C2,8,14,9
DNone of these
Answer: Option A
Explanation:If x is common result, then numbers are 2x, x/2, x+2, x-2
and
2x+ x/2+ x+2+x-2 = 45
4x+x/2 =45
9x =90
x=10
hence numbers are
8,12,5,20
