Question

Si=rupees2115,principal=rupees28200,rate=9%

Answer 1

Step-by-step explanation:

we have given :

principal= ₹28200

rate of interest= 9%

simple interest = ₹ 2115

According to the formula of simple interest,

S.I = P×R×T/100

2115= 28200×9×t/100

2115=282×9×t

2115= 2538×t

t= 2115/ 2538

t= 1.2 years
