Question

Given Principal = RS. 1500, n= 3,
Interest=225, then the rate of simple
interest will be:
O A3
OB) 4
O C) 5
OD) 6​

Answer 1

Step-by-step explanation:

It is given that

SI for 3 years = 225

SI for 2 years = (225×2)/3=150

CI for 2 years = 153

So the difference = 153 - 150 = 3

Here 3 is interest on one year i.e. 75 for one year

We know that

Rate =(SI×100)/(P×t)

Substituting the values

=(3×100)/(75×1)

=4%

SI for 3 years = 225

Rate = 4% p.a.

So Principal = (SI×100)/(R×t)

Substituting the values

=(225×100)/(4×3)

=1875
