The amount of an annuity certain of Rs. 150 for 12 years at 3.5% p.a C...
A = PMT × [(1 + r)n - 1] / r
Where:
- A = Amount of the annuity after n years
- PMT = Annual Payment
- r = Annual Interest Rate (in decimal)
- n = Number of years
Step-by-Step Calculation:
Step 1: Convert the rate to decimal
r = 3.5 / 100 = 0.035
Step 2: Apply the formula
A = 150 × [(1 + 0.035)12 - 1] / 0.035
A = 150 × [(1.035)12 - 1] / 0.035
Step 3: Calculate (1.035)12
(1.035)12 ≈ 1.49957
Step 4: Substitute the value into the formula
A = 150 × [1.49957 - 1] / 0.035
A = 150 × 0.49957 / 0.035 A ≈ 150 ×14.271
A ≈ 2140.65

Use formula ,
amount of an annuity = P[(1 + r/100)ⁿ - 1]/(r/100)
here, P is given initial amount
n is time in years
r is percentage rate per annum.
now, amount of an annuity = 150[(1+3.5/100)^12-1]/(3.5/100)
= 150[(1.035)^12-1]/0.035
= 150(1.511-1)/0.035
= 150 x 0.511/0.035
≈ 2190 Rs
hence, amount of an annuity = 2190 Rs

Given:
Annuity amount = Rs. 150
Number of years = 12
Rate of interest = 3.5% p.a
To find:
Amount after 12 years with compound interest
Formula used:
Amount of annuity = (A/r) x [(1 + r)^n - 1]
where A = annuity amount, r = rate of interest per period, n = number of periods
Calculation:
Here, A = 150, r = 3.5/100 = 0.035 (as rate is given in percentage), n = 12
Amount of annuity = (150/0.035) x [(1 + 0.035)^12 - 1]
= 4285.71
Now, we need to calculate the amount after 12 years with compound interest.
Let the principal amount be P.
We know that:
Amount = P x [(1 + r)^n]
where r = rate of interest per period, n = number of periods
To find P, we can use the following formula:
P = Amount / [(1 + r)^n]
Here, Amount = 4285.71, r = 3.5/100 = 0.035, n = 12
P = 4285.71 / [(1 + 0.035)^12]
= 2190.28
Therefore, the amount of annuity certain of Rs. 150 for 12 years at 3.5% p.a C.I is Rs. 2190.28, which is option A.
