Cost of equity is calculated as -
Cost of equity = Risk free return + Beta * (Market risk - Risk free return)
Given,
Risk free return = 5.3 %
Market risk = 12 %
Beta = 1.05
Cost of equity = 5.3 % + (1.05*(12-5.3%))
Cost of equity = 12.335 % or 12.24 %
From the problem statement it is clear that here we need to find out simple interest rate.
One do not get interest on any investment made at the end of tenure.
Putting this mathematically:
Let amount at the end of 5th year as A
Simple Interest for 5 years, SI = 750 *5
SI = 3750
Hence A = 10000 +3750
A= 13750
Let rate of return = R
Tenure t = 5
But,
A = P(1 + R*t/100)
13750 = 10000( 1+ R*5/100)
13750 = 10000 + 50000R/100
3750 = 500R
R = 3750/500
R = 7.5 %
Hence rate of return is 7.5% per annum (answer)
