Question

A sum of money at 8% simple interest becomes Rs 385 in five years. What was the principle amount invested?​

Answer 1

Answer:

We know that A = P(1+rt/100)

                     12122 = P(1+16/100)

                     P = 10450.

After 2 years 8 months, it will be 10450 * (1 + 8/3 * 9/100)

                                                    = 10450 * 124/100

                                                    = 12958.
