Answer 1

Answer:

sorry dont know

Answer 2

Answer:

The rate of interest per annum is 5% p.a.

Step-by-step explanation:

Assume the amount is at r % simple interest.

The simple interest formula is: $SI = \frac{P\times r\times t}{100}$

Here P = principal, r = interest rate, t = time and SI = interest earned.

Given:

P = 3500

SI = 525

t = 3 years.

Determine the value of r as follows:

$SI = \frac{P\times r\times t}{100}\\525=\frac{3500\times r\times3}{100}\\ r=\frac{525\times100}{3500\times3}\\ =5$

Thus, the rate of interest per annum is 5% p.a.
