Question

calculate the amount and compound interest on Q1. $10,800 for 3 years at 12-1/2percent per annum compound annually. ​

Answer 1

Step-by-step explanation:

Let us assume cost of the tricycle be x.

It is given that it is sold at a gain of 15% = 15x/100.

Also it is given that if it sold for 108 the profit would have been 20% = 20x/100.

20x/100 - 15x/100 = 108

5x/100 = 108

5x = 10800

x = 2160
