Right Answer is: D

SOLUTION

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:-  513 = 132651

⇒ P = Rs. 125000

∴ Sum = Rs. 125000

Given

Amount (A) = Rs 140608

Rate (R) = 8% p.a. = 4% half-yearly

Period (n) ==1 \frac{1}{2} \text { years } = 3 half-year

A = P {1 + (R / 100)}n

140608 = P {1 + (4 / 100)}3

140608 = P (26 / 25)3

Therefore,

P = 140608 × (25 / 26) × (25 / 26) × (25 / 26)

On further calculation, we get,

P = Rs 125000

Hence,

Principal = Rs 125000

How do you calculate compound interest for 1.5 years compounded annually?

Detailed Solution.
Given: P = Rs. 15000, R = 20%, T = 1.5 year..
Concept used: When Calculating semi annually, rate gets halved and time gets doubled..
Calculation: C.I. semi annually ⇒ R = 10%, T = 3 years. C.I. = P [(1 + R/100)T -1] C.I. = 15000[(1 + 10/100)3 -1] = 15000 × (1331 – 1000) × 1000. = 15 × 331. ⇒ C.I. = Rs. 4965..
