Correct Answer - Option 3 : 2
Concept:
Sinking Fund Method:
It is a technique for depreciating an asset while generating enough money to replace it at the end of its useful life. The sinking Fund coefficient(S) for n years is given below the formula
\(S = {i \over {(1+i_s)^n-1}}\)
Where is = interest rate of sinking fund, i = rate of interest, and S = Sinking fund coefficient
Year's Purchase(YP):
It is defined as the capital sum required to be invested in order to receive an annuity of Re 1.00 at a certain rate of interest.
\(YP = {1 \over (i+S)}\)
Where i = rate of interest, and S = Sinking fund coefficient
Calculation:
Given Data
Rate of interest(I) = 7% = 0.07
Coefficient of annual sinking fund(S) = 0.43
So, Year's Purchase(YP)
\(YP = {1 \over (i+S)} = {1 \over (0.07+0.43)} = {1 \over (0.50)}\) = 2
