To determine the value of x, we need to use the formula for the present value (PV) of a perpetuity, which is given by:
PV = \(\frac{x}{r}\)
where x is the payment per period, and r is the interest rate per period. Here, the interest rate is 5% compounded semi-annually, so the semi-annual interest rate is:
r = \(\frac{5}{100 \times 2}\) = 0.025
We are given that the present value of the perpetuity is ₹1,80,000. Substituting the given values into the formula:
1,80,000 = \(\frac{x}{0.025}\)
Solving for x:
x = 1,80,000 \(\times\) 0.025
x = ₹4,500
Thus, the value of x is ₹4,500.
