Question

In what time $3
50 at 5% per annum will amount to 420 ​

Answer 1

Let time be T

Rate = 5&

Amount = 420$

Principal = 350$

Interest = Amount - Principal = 420 - 350 = 70$

T = Interest * 100/ Principal * Rate

T = 70 * 100/ 350 * 5

T = 4 years

(The Simple Interest formulaes have to be learnt well in order to do these sums :) )
