Reena took a loan of Rs. 1200 with simple interest for as many years as the rate of interest. If she paid Rs. 432 as interest at the end of the loan period, what was the rate of interest?
Answer: Option
Explanation:
Let rate = R% and time = R years.
| Then, |  |
1200 x R x R |  |
= 432 |
| 100 |
12R2 = 432
R2 = 36
R = 6.

I= prn/100,
So r=I * 100/pn, atq r=n=x (let),r=36/x as r=n x2=36, x=6.
So r=I * 100/pn, atq r=n=x (let),r=36/x as r=n x2=36, x=6.

@Tejas.
According to question Reena took a loan of Rs. 1200 with simple interest for as many years as the rate of interest.
It means rate of interest and time duration both are equal.

Why should we take R for time why should not T or Something other?

You are right Ppp.
We can also take x.
according to the question R=T.we can take R=T=x
R= S.I*100/P*T
x=432*100/1200*x
x to the power square =36; x= 6
We can also take x.
according to the question R=T.we can take R=T=x
R= S.I*100/P*T
x=432*100/1200*x
x to the power square =36; x= 6

But Why we took R two times in this Solution..
We can Take Like R=Rate of Interest and T=Time
the Formula is SI=PRT/100
In this Formula if We take 1 year then the ans will be 36 instead of 6.
Plz Give me Proper Solution for my biggest Confusion..As Soon As
