Answer 2

⚡Hey mate⚡

✨Here is your answer✨

Time = 8 years

Let the ammount is 100 rupees.

And it's double in 8 years with simple interest.

It means that

Price = 100

Time = 8

Rate =????

Simple interest = 100

Simple interest = price × rate × time ÷ 100

But we want rate then formula is - :



Rate = simple interest × 100 ÷ price × time

Rate = 100 × 100 ÷ 100 × 8

Rate = 12.5 %

Your answer is 12.5 %.
