Assuming by simple you mean there is no compound interest:
4200 x Interest rate = 630/3
4200 x Interest rate = 210
Interest rate = 210/4200
Interest rate = 0.05
Interest rate = 5%
4200 x Interest rate = 630/3
4200 x Interest rate = 210
Interest rate = 210/4200
Interest rate = 0.05
Interest rate = 5%
