Correct Answer - Option 1 : Rs. 13,891.50
Given:
The sum = Rs 12,000
Time = \(1 \frac{1}{2}\) years
Rate = 10% p.a.
Formula used:
A = P(1 + R/100)t
Here, A, P, R and t are the Amount, Principal, Rate and time respectively
Concept used:
When compounded half-yearly then,
Rate is half and time is doubled
Calculation:
Rate = 10%/2 = 5% and Time = \(1 \frac{1}{2}\) × 2 = 3 half yearly
Now, A = P(1 + R/100)t
⇒ A = 12000(1 + 5/100)3
⇒ A = 12000 × 21/20 × 21/20 × 21/20
⇒ A = 13891.5
∴ The total amounts to be paid is Rs 13891.50
