,R=9/200
, T =3 years 4 month's
find simple interest and amount​

Answer 1

Answer:

SI = ₹67.5

A = ₹517.5

Step-by-step explanation:

Given :

P = 450

R = 9/200 = 4.5 %      [(9*100)\200]

T = 3 4/12 = 3 1/3 = 10/3

Formulae :

SI = (P * T* R)/100

A = SI + P

Solution :

SI = (P * T* R)/100 = (450 * 10 * 4.5)/(100*3) = 67.5

A = SI + P = 67.5 + 450 = 517.5
