+//Given Data:-
+        V=40;        //Absolute Velocity of Jet, m/s
+        a=0.04;       //Cross-sectional area of Jet, m^2
+        u=40;          //Speed of boat, km/hr
+
+//Data Used:-
+        rho=1000;      //Density of water, kg/m^3
+
+//Computations:-
+        u=u*1000/3600;         //m/s
+        F=rho*a*(V+u)*V;          //N
+        eta=2*u/(V+2*u)*100;          //in Percentage
+
+//Results:-
+     printf("(a)Propelling Force, F=%.f N \n", F)     //The answer vary due to round off error
+     printf("(b)Efficiency of propulsion, eta=%.2f percent", eta)
