Annual = $68,000
Semiannual = $34,000
Monthly = $5,666.67
Semimonthly or bimonthly = $2,833.33
Weekly = $1,416.67
Let the amount B pays be £x
So,
A pays £125
B pays £x
They pay in the ration 3:2
Therefore,
125/x = 3/2
Cross multiplying we get,
125 x 2 = 3x
3x = 250
x = £63.33
I believe the answer is 5. Hope this was right for you.
