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.

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

Please explain to me.

Why 840 is calculated for 50% of A's share and why not 420?

A=(105*4months)+((105*8months)+50%(105*8months))
=420+(420+840)
=1680

B=40*12months
=480

C=36*12months
=432

now u devide the above values by 48(all 3 values r devided without any fraction value)then u will get 35:10:9....

then add all 3 shares 35+10+9=54

for B share=21600*(B share/total share)
=21600*(10/54)
=4000rs

First find the ratio.

Which is 105:40:36?

They have given A's share increases after 4 months which means for first 4 months it remains same and the next 8 months (as there are 12 months in a year) it increases by 50%, so we need to calculate first for 4 months separately and the for next 8 months after increasing by 50%.

A's contribution for 4 months = 105 * 4 = 420.

A's contribution for remaining 8 months = 105 * 8 = 840.

As A's share increases in this 8 months, we need to calculate it,

840 + (840/2) = 840 + 420 = 1260.

50% increase means 840/2.

Finally for a year=420+1260=1680.

50% increase of 840.

So,

840 + (*820/2) = 820 + 420 = 1260.

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.

Can you please explain why we are changing the ratio into the whole number like 150?
