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.
