Answer:
6.5% per annum
Step-by-step explanation:
Given that the rate of interest when 800 fetches 130 as simple interest in 2 years 6 months.
We need to find out the rate.
Simple interest = Rs. 130, Principal = 800, Time = 2 years 6 months = 2 + 1/2 = 5/2 years
Now,
SI = (P × R × T)/100
Substitute the values,
→ 130 = (800 × R × 5/2)/100
→ 130 = (800R × 5)/200
→ 130(200) = 800R × 5
→ 130(2) = 8R × 5
→ 260 = 40R
→ 26/4 = R
→ 6.5 = R
Therefore, the rate is 6.5% per annum.
