profit will be in ratio
15000:20000:25000 = 3:4:5 {A,B and C respectively}
let total profit is 'x' at end of year
B receives 3040 profit including 7% of working profit
x*7/100 + (93x/100)*4/12 =3040
by solving x= 8000
7% of B = 8000*7% =560
sharable profit = 8000-560 =7440
profit for C = 5/12 * 7440= 3100 , no option is matching.
