Mashcka [7]

Answer:

2 %

Step-by-step explanation:

Money borrowed, Principal, P = $ 700

time of investment, T = 3 years

Total interest paid, Simple interest, S.I = $ 42

Let the rate of interest is R.

Use the formula for simple interest.

S.I. =\frac{P\times R\times T}{100}

By substituting the values

42 =\frac{700\times R\times 3}{100}

4200 = 2100 R

R = 2 %

Thus, the rate of interest is 2%.
