The salary of A, B and C are in continued proportion. If the salery of A and C are respectively $9000 and 4000, then salery of B:
Hello dear
If we concentrate on continuous proportion it means that the proportion of increase is continues.
Example 2;4;6
1;3;5
10;20;30
So according to this if A, B, C must be continuous proportion then the salary of B should be 6500
9000,6500,4000 difference of 2500 in each of them.
Hope this is the correct ans.
Good luck
