Slot – 3 – Quantitative Aptitude – Interest – A person invested a certain amount of money


Q. A person invested a certain amount of money at 10% annual interest, compounded half-yearly. After one and a half years, the interest and principal together became Rs 18522. The amount, in rupees, that the person had invested is?
Answer: 16000

Solutions:
Let the invested amount = P
So 18522 = P (1+10/200)^3
18522 = P*1.05^3
P = 18522/1.05^3
P = 16000
