⚡Hey mate⚡

✨Here is your answer✨

Principle ammount = 300

Simple interest = 45

Time = 3 years

Rate =??????

Formula - :

Simple interest = price × rate × time ÷ 100

But we want rate then formula is

Rate = simple interest × 100 ÷ price × time

Rate = 45 × 100 ÷ 300 × 3

Rate = 5%

Your answer is 5%.
