Question

on what sum will the compound intrest at 10% per annum for 1½ years compounded half yearly be rs 630.50​

Answer 1

Answer:

545

Step-by-step explanation:

A = 630.50

r = 5. ( since half yearly).

n = 3 (since half yearly,. 1.5+1.5=3)

A=P(1+r/100)n (formula)

630.50 = P ( 1+ 5/100)³

630.50 = P ( 1.05 )³

630.50 = P * 1.157625

P = 630.50/1.157625

therefore,. P = 544.64960587

Approximately the answer is, 545
