Question 1; Mark:8
Find the accumulated value when
Rate of interest =5%
Number of periods ānā=20
Amount of annuity R = Rs 5,000
Accumulated value = ?
Rate of interest (i) = 5%
Number of periods(n) = 20
Amount of annuity = 5,000Rs.
Accumulation Factor AF= ((1 + i) ^ n -1) / i
= ((1 + 0.05)^20-1) / 0.05
= 33.0659
Accumulated value = number if period * accumulation factor
= 5,000*33.0659
= 165329.5ans
