(B) Let the total capacity of the tank be $100$ units.$1$. Initially,the tank is filled with $A$ type petrol: $A = 100, B = 0$.$2$. The tank becomes half-empty (remaining $A = 50$) and is filled with $B$ type petrol: $A = 50, B = 50$.$3$. The tank becomes half-empty (remaining $A = 25, B = 25$) and is filled with $A$ type petrol: $A = 25 + 50 = 75, B = 25$.$4$. The tank becomes half-empty (remaining $A = 37.5, B = 12.5$) and is filled with $B$ type petrol: $A = 37.5, B = 12.5 + 50 = 62.5$.Thus,the percentage of $A$ type petrol in the tank is $37.5 \%$.
