Question

1.At what rate of interest will a sum of 1500 amount to 2040 in 8 years?

2.Find the sum which will amount to 9000 in 4 years at 5% per annum?​

Answer 1

Answer:

Idk if it's a problem of simple or Coumpound interest but I guess it's simple interest only

Step-by-step explanation:

sum no 1.

let rate be x

we know what,

SI=A-P

2400-1500=540(which is the interest)

therefore, SI=(P*R*T)/100

substitute the given values,

540=(1500*x*8)100,

x=4

therefore, the rate is 4%

SUM NO 2.

let the sum be X

we know that

A=P+SI

9000=X+(X*5*4)/100

X=7500

therefore, the sum is Rs7500
