A, B and C enter into a partnership in the ratio 
: 
: 
. After 4 months, A increases his share 50%. If the total profit at the end of one year be Rs. 21,600, then B's share in the profit is:
: : . After 4 months, A increases his share 50%. If the total profit at the end of one year be Rs. 21,600, then B's share in the profit is:
Answer: Option
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 x | 10 | |
= Rs. 4000. |
| 54 |

So the ratio of investment of A, B, C is based on the status at the end of the year, no matter what's the share in the middle of it. Suppose A invest very little in the first 11 month, and increase a large amount in the 12th month, then he can still gain a big share of the profit.
So someone explain this.

First divide 1680:480:432
by 48,we wil get 35:10:9
then add al of them we wil get 54
then divide [21600*10 /54]=ans

Find the minimum number that will be divide 2,3 and 5 simultaneously.
That is known as LEAST COMMON DENOMINATOR.It will be 30.
Then 7*15/30,4*10/30,6*6/30. BUT 15,10,6 are by dividing(the given denominator 2,3,5 with LCM=30).
Then we can avoid the common denominator 30,and Finally we can get 105=15*7, 40= 4*10, and 36= 6*6.
Thank you Rocky.

Explain, How 1680:4800:432 comes 35:9:10?

As per question A increase his share 50%, it means A's contribution.
1 year = 12 month.
4 month 105*4 = 420.
Remaining 8 month is 105*8 = 840.
1 year = 12 month.
4 month 105*4 = 420.
Remaining 8 month is 105*8 = 840.

A : B : C = 105x x 4 + 150 x 105x x 8: (40x x 12) : (36x x 12)
= 1680x : 480x : 432x = 35 : 10 : 9.
Anyone explain this step i didn't understand.

I agree @Rangeet. If A's share changes that changes other partners share.
