A perpetuity pays $A per year. Bob, Carol, and Daniel take turns to receive payments from this perpetuity. Bob receives the first n payments, then Carol receives the next n payments, and Daniel receives the next n payments after Carol. After Daniel receives his first n payments, the cycle repeats, and Bob will receive another n payments, followed by Carol and Daniel, and so on. Let r be the discount rate. (i) Express the present value of Bob's payments in terms of A, r, and n. (ii) If it is known that (1+r)^n = 1.25, what is the present value of Carol's payments as a percentage of the original perpetuity?
