Question

1. Find the simple interest and the amount due on 9,000 at 8 % per annum for 1 year 6 months.​

Answer 1

S.I = (P × R × T)/100

R = (S.I × 100)/(P × T)

P = (S.I × 100)/(R × T)

T = (S.I × 100)/(P × R)

If the denotes the amount, then A = P + S.I

apply information given to the equations

Step-by-step explanation:

How to calculate simple interest?

Principal: The money which we deposit in or the lower from the bank or the money learned called the principal.

Answer 2

here P =9000

R= 8 %

N = 1.5 year

by the formula, we have,

I = p × r × n /100

= 9000 × 8 × 1.5/100

I = 1080 ₹

now, A = P + I

A = 9000+1080

A = 10,080 ₹
