Answer 1

This is the case of simple Ci where Ci=A-p

[Latex] A=P*(1+I)^n [/latex]

[Latex] A=5120*(1+0.125)^3[/latex]

A=7290.

Ci=7290-5120=2170

Answer 2

Answer:

The amount of interest paid by him is Rs.7290

Step-by-step explanation:

Principal = Rs.5120

Rate of interest = r = 12.5%

Time = 3 years

Formula : $A=P(1+r)^t$

Where A is the Amount

P is the principal

t is the time

r is the rate of interest in decimals

$A=5120(1+\frac{12.5}{100})^3$

$A=7290$

Hence The amount of interest paid by him is Rs.7290
