Answer:
The Amount is ₹ 13778 & compound Interest is ₹978.
Step-by-step explanation:
SOLUTION :
Given :
Principal, P = ₹ 12800
Time , n =1 yr =1×2=2yr
Rate, R = 7 ½ % = 15/2%
For half yearly :
Time , n = 1× 2 = 2yr
Rate, R = 15/2% × ½ = 15/4%
A = P(1+ R /100)ⁿ
A = 12800(1 + 15/4×100)²
A = 12800(1 + 15/400)²
A = 12800 [(400 + 15)/400]²
A = 12800 [415/400]²
A = 12800 × 415 × 415/ (400 × 400)
Amount, A = ₹ 13778
compound Interest , C.I = A - P
C.I = 13778 - 12800
C.I = ₹ 978
Hence, the Amount is ₹ 13778 & compound Interest is ₹978.
