3.
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:
Rs. 2100
Rs. 2400
Rs. 3600
Rs. 4000
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.

The LCM of the denominators:

Step-1:
2,3,5=30 and multiply each term by 30
(7/2)*30 = 105, (4/3)*30 = 40, (6/5)*30 = 36
So, capital ratio = 105: 40: 36.

Step-2:
A initially invests 105 for the first 4 months + then increases it by 50%, means 50% of 105 i.e,.(50/100)*105 = 52.5.
So his new capital is 105 + 52.5 = 157.5 (this new amount is invested for the remaining 8 months).

First 4 months:
105×4=420

Next 8 months (after increase):
157.5×8=1260
Total = 420 +1260 = 1680

B invested ₹40 for 12 months:
40 × 12 = 480

C invested ₹36 for 12 months:
36 × 12 = 432

Now we have:
A:B:C = 1680:480:432
= 35 : 10 : 9.

Total profit = Rs. 21,600.
The ratio sum = 35+10+9 = 54 parts.
value of 1 part = 21600/54 = 400,
So B’s share is 10 * 400 = 4000.

Question says A increases his profit by 50%, not his investment by 50%.

Please explain to me.

Please give a clear information.

An easy way;

A = 7/2 * 4+ 7/2 * 3/2*8 = 14 + 42 = 56.
B = 4/3*12 = 16.
C = 6/5*12 = 14.4,
Total = 56 + 16 + 14.4 = 86.4
So, 86.4 = 21600,
Then B's Share 16 = 4000 (Ans)

The question can be a bit misleading. It has to be specified that A's share increases without a reduction in the shares of B and C, with the total amount of investment increasing as a result. Without this clarification, it could well be that A's share increases at the expense of the others' shares and that the total level of investment remains the same.

105x*8 ?

Here we need to find A, (1year=12months) so after 4 months means remaining 8 months.

& Then multiple with 2 b/c in this 8 months 50% more.

Why 105x * 8?
