Question

what principal will amount to rs900 in 6 years at10% simple intrerest

Answer 1

Given:

A=Rs 900

t=6 years

r=10%

We know that :

I=P*R*t/100

==)I=P*10*6/100

==)I=P*60/100.............(1)

We also know:

A=P+I

900=P+I

==)P=900-I..........(2)

Inserting the value of P in 1 we get:-

I=(900-I)*60/100

==)100*I=54000-60I

==)160I=54000

==)I=54000/160

==)I=337.5

Hope it helps
