Answer 2

Given :-

• Principal = Rs 8000
• Simple Interest = Rs 4000
• Time = 3 years

To Find :-

• Rate of Interest

Solution :-

➞ Simple Interest = P × R × T / 100

➞ 4000 = 8000 × Rate × 3 / 100

➞ 4000 = 80 × Rate × 3

➞ 4000 = 240 × Rate

➞ 4000 / 240 = Rate

➞ 400 / 24 = Rate

➞ 16.66% = Rate

Thus Rate of Interest = 16.66%
