Answer 1

Answer:

2000

Step-by-step explanation:

Let the principal be 'p'

Simple Interest = P*N*R/100

I = p*5*9/100

|= = 45p/100

Now,

Amount = Simple interest + Principal

17400 = 45p/100 + p

17400 = 100p + 45p/100

17400 = 145p/100

17400*100/145 = p

3480*100/29 = p

20*100 = p

2000 = p
