Answer:

Given,

A= 5070 Rs

Time = 18 months = 3/2 years

A = P+ SI  

5070 = P + PrT /100 --------------(i)

P= Pr× 3 / 100×2

5610 = P +PR × 9/100 × 2  ------------- (ii)

subtracting we get

540= 6rR/ 100

Pr =18000

from equation (i)

5070 = P + 54000/200

P = 5070-270 =4800

r=18000/4800

=> 3.75%
