Answer:
58.33%
Step-by-step explanation:
A's Contribution = 2700
B's Contribution= 1800
Ratio = 7:5
Profit = 900
Total Ratio = 7+5 = 12
First , Calculate both share of the profit.
A's Share= 7/12 ×900
525
B's share= 5/12 ×900
375
Now , express A's Share as a percentage
A's Share= 525/900 ×100
58.33%
