Answer:
Sum = Rs. 125000
Explanation:
Given
Amounts = Rs. 1,32,651
Time = 3/2 years
Rate = 4%
Compounded half yearly
Concept
A = P × (1 + r/100)t
When compounded half yearly
Rate become half and Time become double (As in 1 year 12 months = 6 months + 6 months)
Calculation
Time = 3 years
Rate = 2%
⇒ 132651 = P × (1 + (2/100))^3
⇒ 132651 = P × (1 + (1/50))^3
⇒ 132651 = P × (51/50)^3
⇒ P = (132651 × 50 × 50 × 50)/(51 × 51 × 51)
Note:- 51^3 = 132651
⇒ P = Rs. 125000
∴ Sum = Rs. 125000
