Answer:
90
Step-by-step explanation:
Let C be the total of what they share.
Let A be the first
Let B be the second
A : B = 10 : 3
Total ratio = 10 + 3 = 13
From the question, were told that the first (i.e A) receives 300. Now we use this info to obtain the total of what they share as follows
A share is given by
(A ratio / total ratio) x total of what they share (C)
10/13 x C = 300
10C / 13 = 300
Cross multiply
10C = 13 x 300
10C = 3900
Divide both side by 10
C = 3900/10
C = 390
Now we can solve for B's share as
3/13 x 390 = 90
Therefore, the second obtained 90
