Dear Visheshh,
Assuming that the Truck is moving with constant Power (P), and assuming that F is the resistive force acting on the truck,
P = F x Velocity
P = (η xN) x 10, where η = dynamic friction, N = Normal Reaction = 200 kg xg
P = η x 200g x 10...........(1)
After 50 seconds, the power remaining same,
P = η x 100g x V...........(2), where V is the velocity after 100 Kg of water is unloaded in 50 seconds
Equating (1) and (2), Velocity V = 20 m/s
