Final answer:
The simple interest for a principal amount of S700, with an interest rate of 6% and a time period of 3 years, is S126.
Step-by-step explanation:
To find the simple interest (I) for a principal amount (P) of $S700, with an interest rate (r) of 6% and a time period (t) of 3 years, we can use the formula I = P * r * t / 100.
Substituting the values into the formula: I = S700 * 6 * 3 / 100 = S126.
Therefore, the simple interest is S126.
