A+B+C = 1105
Given ratio 11:18:24
Let us say the shares of A,B,C deducting 10,20,15 be a,b,c
a+b+c = 1105-45= 1060 = 53K
c share = (1060X24)/53 = 480
C = charlie share = 480+15 = 495
Option D

(11x+10)+(18x+20)+(24x+15)=1105
53x=1060
x=20
24*20+15=495

Answer D.

How much did Charlie receive initially or after the distribution needs to be made clear ! How are we ascertaining that the initial amount received by Charlie is being asked for ?

Hi stne

It is written that the three friends divide $1105 among themselves.
We are told that if the $10,$20, and $15 is reduced from their original share,
the ratio of their sums will become 11:18:24(as it changes from the original)

If they needed us to find out what his current share is - after the reduction
it would have read "what will Charlie's share after the amount is reduced"

Hope this helps you!

Sorry , this is not convincing ,
I would make a similar argument :
If they wanted us to find the initial amount , the question would have asked what was Charlie's amount before the division or what was Charlie's original amount . With out the OA you would not know what is actually being asked .

Check out these similar questions , clearly mentioning the requirement

total money divided is 1105 among three friends in the share of 11:18:24 but excluding 10, 20 and 15 usd, so lets take out these amount for now from total. 1105-45(10+20+15), we get 1060 divided according to the ratio above. 11x+18x+24x=53x=1060 or x=1060/53 or x=20. Now we know that 24*20 is 480+15 that we excluded, we get 495 usd that the third person received

I attempted the question without calculation. Roughly the ratio between the three division is given. As the amount received by Charlie if reduced by 15, it should be a factor of 24. Hence, only b and d are left, others if reduced by 15 is not even an even no. Now, 24 is little less than 50% of sum of ratio of all three. And, 480 is also little less than 50% of 1060. Hence, I go with D.
