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?
While traveling at uniform speed. U read a two digit no. after one hr the number is reversed order. After another hour the number read is same two digit number. What is the average speed?

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

As many years as the rate of interest so we taken t=r

According to ques we can also take x, y, z it is not a matter.

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

Hai friends
Actually reena took sum of Rs.1200 ie P=1200 and paid simple interest of Rs.432
We are asked to find the rate ie R
It is given that, simple interest for as many years as the rate of interest. this line mean that T=R.
Or
you can asuume R & T to some other variable also ie R=T=x
formulato be used is SI=PRT/100
432=1200*R*R/100 (Here i have used T=R)
43200=1200 R square
Rsquare=43200/1200
Rsquare=36
R=6
Hope understand... Goood night
12R2 = 432
