Answer 1

Answer:

Principal=Rupees 375 and Amount=375+90=465

Step-by-step explanation:

Give,

Simple Interest(SI)=Rupees 90

Rate(R)=6%

Time(T)=4 yrs

Principal(P)=?

Amount(A)=?

We know that,

SI=PRT/100

let the principal be 'P'

Now,

90=(P*6*4)/100

90=P*24/100

90*100=24P

9000=24P

9000/24=P

375=P

∴Principal=Rupees  375

Again,

Amount(A)=?

We know that,

A=P+I(where P stands for Principal and I for Interest)

A=375+90

A=465

∴Amount=Rupees 465
