Here's how to approach the problem:
Given:
1. The Main wallet initially holds m% of its capacity.
2. The Backup wallet initially holds b% of its capacity.
3. After a transfer, the Main wallet reaches 100% , and the Backup wallet ends up with b/2% of value .
Constraints:
1. Backup initially held a higher percentage than the Main: b>m
2. After the transfer:
Main wallet's increase = Backup wallet's decrease:
b/2 (Transferred amount)+m=100
b=2(100-m)
Steps:
1. Plug in the possible values of (30, 45, 50, 55, 60) and calculate b.
2. Ensure b>m to satisfy the initial condition.
Calculation:
For m=30 :
b=2(100-30)=140
This is not one of the options provided even though b>m & hence can be eliminated
For m=45:
b = 2(100 - 45) = 2(55) = 110
This is not one of the options provided even though b>m & hence can be eliminated
For m=50:
b = 2(100 - 50) = 2(50) = 100
This is not one of the options provided even though b>m & hence can be eliminated
For m=55:
b = 2(100 - 55) = 2(45) = 90
This is one of the options provided & hence is a valid answer as it also satifies the constraint of b>m
For m=60:
b = 2(100 - 60) = 2(40) = 80.
This is not one of the options provided even though b>m & hence can be eliminated
Answer:
Hence the only possible pair of options & henceforth the answer is:
b=90
m=55.
