Answer: 7 years
Step-by-step explanation:
Given the formula for simple interest as
Principal × Rate × Time
To find Time is therefore 100 × Interest/ Principal x Rate
From the above question,
Principal is given as 600;
Interest is 294 and
Rate is 7%
Slot the values into the formula:
100 × 294/ 600 x 7
= 29400/4200
=7
Therefore, Time (T) is 7 years
I hope this is clear, please mark as brainliest
