Q16 of 110 Page 41

A person has deposited ₹25,000 in an investment which yields 14% simple interest annually. Do these amounts (principal + interest) form an A.P.? If so, determine the amount of investment after 20 years.

Yes, the amounts form an A.P.


Given principal, p = Rs. 25,000


Simple Interest, r = 14%


Time, t = 20 years


We know that Total amount = p (1 + )


⇒ Total Amount = 25000 (1 + )


= 25000 (1 + )


= 25000 ()


= 95000


∴ Amount of investment after 20 years = Rs. 95, 000
